Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530748, here are decompositions:

  • 47 + 31530701 = 31530748
  • 89 + 31530659 = 31530748
  • 107 + 31530641 = 31530748
  • 131 + 31530617 = 31530748
  • 251 + 31530497 = 31530748
  • 269 + 31530479 = 31530748
  • 311 + 31530437 = 31530748
  • 401 + 31530347 = 31530748

Showing the first eight; more decompositions exist.
