Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27480, here are decompositions:

  • 23 + 27457 = 27480
  • 31 + 27449 = 27480
  • 43 + 27437 = 27480
  • 53 + 27427 = 27480
  • 71 + 27409 = 27480
  • 73 + 27407 = 27480
  • 83 + 27397 = 27480
  • 113 + 27367 = 27480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27480 first appears in π at position 21,279 of the decimal expansion (the 21,279ordinal-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.
