Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178252, here are decompositions:

  • 3 + 178249 = 178252
  • 5 + 178247 = 178252
  • 29 + 178223 = 178252
  • 83 + 178169 = 178252
  • 101 + 178151 = 178252
  • 149 + 178103 = 178252
  • 251 + 178001 = 178252
  • 359 + 177893 = 178252

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 178,252 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 178252 first appears in π at position 518,129 of the decimal expansion (the 518,129ordinal-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.
