Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27540, here are decompositions:

  • 11 + 27529 = 27540
  • 13 + 27527 = 27540
  • 31 + 27509 = 27540
  • 53 + 27487 = 27540
  • 59 + 27481 = 27540
  • 61 + 27479 = 27540
  • 83 + 27457 = 27540
  • 103 + 27437 = 27540

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27540 first appears in π at position 58,300 of the decimal expansion (the 58,300ordinal-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.
