Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28110, here are decompositions:

  • 11 + 28099 = 28110
  • 13 + 28097 = 28110
  • 23 + 28087 = 28110
  • 29 + 28081 = 28110
  • 41 + 28069 = 28110
  • 53 + 28057 = 28110
  • 59 + 28051 = 28110
  • 79 + 28031 = 28110

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28110 first appears in π at position 38,970 of the decimal expansion (the 38,970ordinal-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.
