Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516164, here are decompositions:

  • 5 + 31516159 = 31516164
  • 7 + 31516157 = 31516164
  • 11 + 31516153 = 31516164
  • 41 + 31516123 = 31516164
  • 61 + 31516103 = 31516164
  • 83 + 31516081 = 31516164
  • 103 + 31516061 = 31516164
  • 137 + 31516027 = 31516164

Showing the first eight; more decompositions exist.
