Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133618, here are decompositions:

  • 47 + 133571 = 133618
  • 59 + 133559 = 133618
  • 137 + 133481 = 133618
  • 167 + 133451 = 133618
  • 179 + 133439 = 133618
  • 227 + 133391 = 133618
  • 239 + 133379 = 133618
  • 269 + 133349 = 133618

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 133,618 and was likely granted around 1872.

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

Position in π

The digit sequence 133618 first appears in π at position 60,518 of the decimal expansion (the 60,518ordinal-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.
