Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27438, here are decompositions:

  • 7 + 27431 = 27438
  • 11 + 27427 = 27438
  • 29 + 27409 = 27438
  • 31 + 27407 = 27438
  • 41 + 27397 = 27438
  • 71 + 27367 = 27438
  • 101 + 27337 = 27438
  • 109 + 27329 = 27438

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27438 first appears in π at position 34,854 of the decimal expansion (the 34,854ordinal-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.
