Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61472, here are decompositions:

  • 3 + 61469 = 61472
  • 31 + 61441 = 61472
  • 109 + 61363 = 61472
  • 139 + 61333 = 61472
  • 181 + 61291 = 61472
  • 211 + 61261 = 61472
  • 241 + 61231 = 61472
  • 331 + 61141 = 61472

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61472 first appears in π at position 28,089 of the decimal expansion (the 28,089ordinal-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.
