Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30312, here are decompositions:

  • 5 + 30307 = 30312
  • 19 + 30293 = 30312
  • 41 + 30271 = 30312
  • 43 + 30269 = 30312
  • 53 + 30259 = 30312
  • 59 + 30253 = 30312
  • 71 + 30241 = 30312
  • 89 + 30223 = 30312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30312 first appears in π at position 45,575 of the decimal expansion (the 45,575ordinal-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.
