Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149618, here are decompositions:

  • 67 + 149551 = 149618
  • 97 + 149521 = 149618
  • 127 + 149491 = 149618
  • 199 + 149419 = 149618
  • 241 + 149377 = 149618
  • 277 + 149341 = 149618
  • 331 + 149287 = 149618
  • 349 + 149269 = 149618

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 149,618 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 149618 first appears in π at position 633,338 of the decimal expansion (the 633,338ordinal-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.
