Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576, here are decompositions:

  • 3 + 31573 = 31576
  • 29 + 31547 = 31576
  • 59 + 31517 = 31576
  • 107 + 31469 = 31576
  • 179 + 31397 = 31576
  • 197 + 31379 = 31576
  • 239 + 31337 = 31576
  • 257 + 31319 = 31576

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31576 first appears in π at position 190,064 of the decimal expansion (the 190,064ordinal-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.
