Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487862, here are decompositions:

  • 19 + 487843 = 487862
  • 31 + 487831 = 487862
  • 43 + 487819 = 487862
  • 73 + 487789 = 487862
  • 79 + 487783 = 487862
  • 181 + 487681 = 487862
  • 211 + 487651 = 487862
  • 373 + 487489 = 487862

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 487,862 and was likely granted around 1892.

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

Position in π

The digit sequence 487862 first appears in π at position 571,919 of the decimal expansion (the 571,919ordinal-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.
