Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999144, here are decompositions:

  • 11 + 999133 = 999144
  • 43 + 999101 = 999144
  • 53 + 999091 = 999144
  • 61 + 999083 = 999144
  • 101 + 999043 = 999144
  • 137 + 999007 = 999144
  • 193 + 998951 = 999144
  • 197 + 998947 = 999144

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 999,144 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 999144 first appears in π at position 529,912 of the decimal expansion (the 529,912ordinal-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.
