Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529710, here are decompositions:

  • 29 + 31529681 = 31529710
  • 41 + 31529669 = 31529710
  • 59 + 31529651 = 31529710
  • 239 + 31529471 = 31529710
  • 263 + 31529447 = 31529710
  • 389 + 31529321 = 31529710
  • 431 + 31529279 = 31529710
  • 461 + 31529249 = 31529710

Showing the first eight; more decompositions exist.
