Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474, here are decompositions:

  • 5 + 31469 = 31474
  • 83 + 31391 = 31474
  • 137 + 31337 = 31474
  • 167 + 31307 = 31474
  • 197 + 31277 = 31474
  • 227 + 31247 = 31474
  • 251 + 31223 = 31474
  • 281 + 31193 = 31474

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31474 first appears in π at position 245,407 of the decimal expansion (the 245,407ordinal-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.
