Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27490, here are decompositions:

  • 3 + 27487 = 27490
  • 11 + 27479 = 27490
  • 41 + 27449 = 27490
  • 53 + 27437 = 27490
  • 59 + 27431 = 27490
  • 83 + 27407 = 27490
  • 191 + 27299 = 27490
  • 251 + 27239 = 27490

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27490 first appears in π at position 40,038 of the decimal expansion (the 40,038ordinal-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.
