Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596780, here are decompositions:

  • 11 + 31596769 = 31596780
  • 23 + 31596757 = 31596780
  • 29 + 31596751 = 31596780
  • 31 + 31596749 = 31596780
  • 37 + 31596743 = 31596780
  • 67 + 31596713 = 31596780
  • 71 + 31596709 = 31596780
  • 73 + 31596707 = 31596780

Showing the first eight; more decompositions exist.
