Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33440, here are decompositions:

  • 13 + 33427 = 33440
  • 31 + 33409 = 33440
  • 37 + 33403 = 33440
  • 97 + 33343 = 33440
  • 109 + 33331 = 33440
  • 139 + 33301 = 33440
  • 151 + 33289 = 33440
  • 193 + 33247 = 33440

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33440 first appears in π at position 48,899 of the decimal expansion (the 48,899ordinal-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.
