Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487992, here are decompositions:

  • 13 + 487979 = 487992
  • 19 + 487973 = 487992
  • 59 + 487933 = 487992
  • 101 + 487891 = 487992
  • 103 + 487889 = 487992
  • 149 + 487843 = 487992
  • 163 + 487829 = 487992
  • 173 + 487819 = 487992

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 487,992 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 487992 first appears in π at position 453,345 of the decimal expansion (the 453,345ordinal-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.
