Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512842, here are decompositions:

  • 23 + 512819 = 512842
  • 101 + 512741 = 512842
  • 131 + 512711 = 512842
  • 179 + 512663 = 512842
  • 233 + 512609 = 512842
  • 251 + 512591 = 512842
  • 263 + 512579 = 512842
  • 269 + 512573 = 512842

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 512,842 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 512842 first appears in π at position 143,474 of the decimal expansion (the 143,474ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
