Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28412, here are decompositions:

  • 3 + 28409 = 28412
  • 19 + 28393 = 28412
  • 61 + 28351 = 28412
  • 103 + 28309 = 28412
  • 193 + 28219 = 28412
  • 211 + 28201 = 28412
  • 229 + 28183 = 28412
  • 313 + 28099 = 28412

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28412 first appears in π at position 135,726 of the decimal expansion (the 135,726ordinal-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.
