Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178362, here are decompositions:

  • 11 + 178351 = 178362
  • 13 + 178349 = 178362
  • 29 + 178333 = 178362
  • 61 + 178301 = 178362
  • 73 + 178289 = 178362
  • 101 + 178261 = 178362
  • 103 + 178259 = 178362
  • 113 + 178249 = 178362

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 178,362 and was likely granted around 1875.

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

Position in π

The digit sequence 178362 first appears in π at position 492,418 of the decimal expansion (the 492,418ordinal-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.
