Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27450, here are decompositions:

  • 13 + 27437 = 27450
  • 19 + 27431 = 27450
  • 23 + 27427 = 27450
  • 41 + 27409 = 27450
  • 43 + 27407 = 27450
  • 53 + 27397 = 27450
  • 83 + 27367 = 27450
  • 89 + 27361 = 27450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27450 first appears in π at position 36,491 of the decimal expansion (the 36,491ordinal-suffix:st 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.
