Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21414, here are decompositions:

  • 7 + 21407 = 21414
  • 13 + 21401 = 21414
  • 17 + 21397 = 21414
  • 23 + 21391 = 21414
  • 31 + 21383 = 21414
  • 37 + 21377 = 21414
  • 67 + 21347 = 21414
  • 73 + 21341 = 21414

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 21414 first appears in π at position 52,637 of the decimal expansion (the 52,637ordinal-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.
