Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188506, here are decompositions:

  • 23 + 188483 = 188506
  • 47 + 188459 = 188506
  • 89 + 188417 = 188506
  • 137 + 188369 = 188506
  • 173 + 188333 = 188506
  • 233 + 188273 = 188506
  • 257 + 188249 = 188506
  • 317 + 188189 = 188506

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 188,506 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 188506 first appears in π at position 540,011 of the decimal expansion (the 540,011ordinal-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.
