Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32400, here are decompositions:

  • 19 + 32381 = 32400
  • 23 + 32377 = 32400
  • 29 + 32371 = 32400
  • 31 + 32369 = 32400
  • 37 + 32363 = 32400
  • 41 + 32359 = 32400
  • 47 + 32353 = 32400
  • 59 + 32341 = 32400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 32400 first appears in π at position 113,466 of the decimal expansion (the 113,466ordinal-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.
