Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88642, here are decompositions:

  • 53 + 88589 = 88642
  • 149 + 88493 = 88642
  • 173 + 88469 = 88642
  • 179 + 88463 = 88642
  • 263 + 88379 = 88642
  • 353 + 88289 = 88642
  • 383 + 88259 = 88642
  • 401 + 88241 = 88642

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 88642 first appears in π at position 62,385 of the decimal expansion (the 62,385ordinal-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.
