Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27530, here are decompositions:

  • 3 + 27527 = 27530
  • 43 + 27487 = 27530
  • 73 + 27457 = 27530
  • 103 + 27427 = 27530
  • 163 + 27367 = 27530
  • 193 + 27337 = 27530
  • 271 + 27259 = 27530
  • 277 + 27253 = 27530

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27530 first appears in π at position 16,681 of the decimal expansion (the 16,681ordinal-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.
