Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27908, here are decompositions:

  • 7 + 27901 = 27908
  • 61 + 27847 = 27908
  • 109 + 27799 = 27908
  • 157 + 27751 = 27908
  • 211 + 27697 = 27908
  • 277 + 27631 = 27908
  • 367 + 27541 = 27908
  • 379 + 27529 = 27908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27908 first appears in π at position 5,470 of the decimal expansion (the 5,470ordinal-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.
