Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28274, here are decompositions:

  • 73 + 28201 = 28274
  • 151 + 28123 = 28274
  • 163 + 28111 = 28274
  • 193 + 28081 = 28274
  • 223 + 28051 = 28274
  • 277 + 27997 = 28274
  • 307 + 27967 = 28274
  • 313 + 27961 = 28274

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28274 first appears in π at position 39,459 of the decimal expansion (the 39,459ordinal-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.
