Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512870, here are decompositions:

  • 67 + 512803 = 512870
  • 73 + 512797 = 512870
  • 103 + 512767 = 512870
  • 109 + 512761 = 512870
  • 157 + 512713 = 512870
  • 199 + 512671 = 512870
  • 229 + 512641 = 512870
  • 277 + 512593 = 512870

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 512,870 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 512870 first appears in π at position 114,088 of the decimal expansion (the 114,088ordinal-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.
