Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617956, here are decompositions:

  • 3 + 31617953 = 31617956
  • 67 + 31617889 = 31617956
  • 79 + 31617877 = 31617956
  • 103 + 31617853 = 31617956
  • 193 + 31617763 = 31617956
  • 199 + 31617757 = 31617956
  • 277 + 31617679 = 31617956
  • 283 + 31617673 = 31617956

Showing the first eight; more decompositions exist.
