Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532710, here are decompositions:

  • 17 + 31532693 = 31532710
  • 23 + 31532687 = 31532710
  • 71 + 31532639 = 31532710
  • 113 + 31532597 = 31532710
  • 137 + 31532573 = 31532710
  • 233 + 31532477 = 31532710
  • 281 + 31532429 = 31532710
  • 431 + 31532279 = 31532710

Showing the first eight; more decompositions exist.
