Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28234, here are decompositions:

  • 5 + 28229 = 28234
  • 23 + 28211 = 28234
  • 53 + 28181 = 28234
  • 71 + 28163 = 28234
  • 83 + 28151 = 28234
  • 137 + 28097 = 28234
  • 233 + 28001 = 28234
  • 251 + 27983 = 28234

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28234 first appears in π at position 30,759 of the decimal expansion (the 30,759ordinal-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.
