Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154018, here are decompositions:

  • 17 + 154001 = 154018
  • 71 + 153947 = 154018
  • 89 + 153929 = 154018
  • 107 + 153911 = 154018
  • 131 + 153887 = 154018
  • 269 + 153749 = 154018
  • 317 + 153701 = 154018
  • 461 + 153557 = 154018

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 154,018 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 154018 first appears in π at position 828,761 of the decimal expansion (the 828,761ordinal-suffix:st 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.
