Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990102, here are decompositions:

  • 59 + 990043 = 990102
  • 79 + 990023 = 990102
  • 89 + 990013 = 990102
  • 101 + 990001 = 990102
  • 103 + 989999 = 990102
  • 131 + 989971 = 990102
  • 151 + 989951 = 990102
  • 163 + 989939 = 990102

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 990,102 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 990102 first appears in π at position 70,755 of the decimal expansion (the 70,755ordinal-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.
