Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599646, here are decompositions:

  • 17 + 31599629 = 31599646
  • 47 + 31599599 = 31599646
  • 83 + 31599563 = 31599646
  • 257 + 31599389 = 31599646
  • 293 + 31599353 = 31599646
  • 587 + 31599059 = 31599646
  • 719 + 31598927 = 31599646
  • 773 + 31598873 = 31599646

Showing the first eight; more decompositions exist.
