Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28358, here are decompositions:

  • 7 + 28351 = 28358
  • 61 + 28297 = 28358
  • 79 + 28279 = 28358
  • 139 + 28219 = 28358
  • 157 + 28201 = 28358
  • 271 + 28087 = 28358
  • 277 + 28081 = 28358
  • 307 + 28051 = 28358

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28358 first appears in π at position 17,795 of the decimal expansion (the 17,795ordinal-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.
