Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170542, here are decompositions:

  • 3 + 170539 = 170542
  • 5 + 170537 = 170542
  • 59 + 170483 = 170542
  • 101 + 170441 = 170542
  • 149 + 170393 = 170542
  • 173 + 170369 = 170542
  • 179 + 170363 = 170542
  • 191 + 170351 = 170542

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 170,542 and was likely granted around 1874.

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

Position in π

The digit sequence 170542 first appears in π at position 83,692 of the decimal expansion (the 83,692ordinal-suffix:nd 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.
