Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149188, here are decompositions:

  • 5 + 149183 = 149188
  • 29 + 149159 = 149188
  • 89 + 149099 = 149188
  • 101 + 149087 = 149188
  • 131 + 149057 = 149188
  • 167 + 149021 = 149188
  • 191 + 148997 = 149188
  • 197 + 148991 = 149188

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 149,188 and was likely granted around 1873.

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

Position in π

The digit sequence 149188 first appears in π at position 477,507 of the decimal expansion (the 477,507ordinal-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.
