Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999198, here are decompositions:

  • 17 + 999181 = 999198
  • 29 + 999169 = 999198
  • 97 + 999101 = 999198
  • 107 + 999091 = 999198
  • 131 + 999067 = 999198
  • 149 + 999049 = 999198
  • 191 + 999007 = 999198
  • 229 + 998969 = 999198

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 999,198 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 999198 first appears in π at position 764,224 of the decimal expansion (the 764,224ordinal-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.
