Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28046, here are decompositions:

  • 19 + 28027 = 28046
  • 79 + 27967 = 28046
  • 103 + 27943 = 28046
  • 127 + 27919 = 28046
  • 163 + 27883 = 28046
  • 199 + 27847 = 28046
  • 223 + 27823 = 28046
  • 229 + 27817 = 28046

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28046 first appears in π at position 32,505 of the decimal expansion (the 32,505ordinal-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.
