Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80258, here are decompositions:

  • 7 + 80251 = 80258
  • 19 + 80239 = 80258
  • 37 + 80221 = 80258
  • 67 + 80191 = 80258
  • 109 + 80149 = 80258
  • 151 + 80107 = 80258
  • 181 + 80077 = 80258
  • 271 + 79987 = 80258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80258 first appears in π at position 53,285 of the decimal expansion (the 53,285ordinal-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.
