Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546, here are decompositions:

  • 3 + 31543 = 31546
  • 5 + 31541 = 31546
  • 29 + 31517 = 31546
  • 149 + 31397 = 31546
  • 167 + 31379 = 31546
  • 227 + 31319 = 31546
  • 239 + 31307 = 31546
  • 269 + 31277 = 31546

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31546 first appears in π at position 121,392 of the decimal expansion (the 121,392ordinal-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.
