Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473816, here are decompositions:

  • 5 + 31473811 = 31473816
  • 7 + 31473809 = 31473816
  • 37 + 31473779 = 31473816
  • 83 + 31473733 = 31473816
  • 109 + 31473707 = 31473816
  • 113 + 31473703 = 31473816
  • 223 + 31473593 = 31473816
  • 233 + 31473583 = 31473816

Showing the first eight; more decompositions exist.
