Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178534, here are decompositions:

  • 3 + 178531 = 178534
  • 47 + 178487 = 178534
  • 53 + 178481 = 178534
  • 131 + 178403 = 178534
  • 137 + 178397 = 178534
  • 173 + 178361 = 178534
  • 227 + 178307 = 178534
  • 233 + 178301 = 178534

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 178,534 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 178534 first appears in π at position 23,872 of the decimal expansion (the 23,872ordinal-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.
