Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135558, here are decompositions:

  • 47 + 135511 = 135558
  • 61 + 135497 = 135558
  • 79 + 135479 = 135558
  • 89 + 135469 = 135558
  • 97 + 135461 = 135558
  • 109 + 135449 = 135558
  • 127 + 135431 = 135558
  • 131 + 135427 = 135558

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 135,558 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 135558 first appears in π at position 958,567 of the decimal expansion (the 958,567ordinal-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.
