Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88220, here are decompositions:

  • 43 + 88177 = 88220
  • 103 + 88117 = 88220
  • 127 + 88093 = 88220
  • 151 + 88069 = 88220
  • 229 + 87991 = 88220
  • 277 + 87943 = 88220
  • 367 + 87853 = 88220
  • 409 + 87811 = 88220

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 88220 first appears in π at position 10,563 of the decimal expansion (the 10,563ordinal-suffix:rd 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.
