Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526668, here are decompositions:

  • 179 + 31526489 = 31526668
  • 191 + 31526477 = 31526668
  • 281 + 31526387 = 31526668
  • 317 + 31526351 = 31526668
  • 461 + 31526207 = 31526668
  • 479 + 31526189 = 31526668
  • 599 + 31526069 = 31526668
  • 617 + 31526051 = 31526668

Showing the first eight; more decompositions exist.
