Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160538, here are decompositions:

  • 31 + 160507 = 160538
  • 97 + 160441 = 160538
  • 151 + 160387 = 160538
  • 181 + 160357 = 160538
  • 229 + 160309 = 160538
  • 307 + 160231 = 160538
  • 331 + 160207 = 160538
  • 337 + 160201 = 160538

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 160,538 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 160538 first appears in π at position 260,384 of the decimal expansion (the 260,384ordinal-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.
