Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512858, here are decompositions:

  • 37 + 512821 = 512858
  • 61 + 512797 = 512858
  • 79 + 512779 = 512858
  • 97 + 512761 = 512858
  • 277 + 512581 = 512858
  • 337 + 512521 = 512858
  • 439 + 512419 = 512858
  • 547 + 512311 = 512858

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 512,858 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 512858 first appears in π at position 49,496 of the decimal expansion (the 49,496ordinal-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.
