Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178852, here are decompositions:

  • 53 + 178799 = 178852
  • 59 + 178793 = 178852
  • 71 + 178781 = 178852
  • 239 + 178613 = 178852
  • 251 + 178601 = 178852
  • 281 + 178571 = 178852
  • 293 + 178559 = 178852
  • 383 + 178469 = 178852

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 178,852 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 178852 first appears in π at position 13,130 of the decimal expansion (the 13,130ordinal-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.
