Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999018, here are decompositions:

  • 11 + 999007 = 999018
  • 29 + 998989 = 999018
  • 61 + 998957 = 999018
  • 67 + 998951 = 999018
  • 71 + 998947 = 999018
  • 101 + 998917 = 999018
  • 109 + 998909 = 999018
  • 157 + 998861 = 999018

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 999,018 and was likely granted around 1911.

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

Position in π

The digit sequence 999018 first appears in π at position 556,999 of the decimal expansion (the 556,999ordinal-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.
