Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28350, here are decompositions:

  • 31 + 28319 = 28350
  • 41 + 28309 = 28350
  • 43 + 28307 = 28350
  • 53 + 28297 = 28350
  • 61 + 28289 = 28350
  • 67 + 28283 = 28350
  • 71 + 28279 = 28350
  • 73 + 28277 = 28350

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28350 first appears in π at position 146,256 of the decimal expansion (the 146,256ordinal-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.
