Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516304, here are decompositions:

  • 7 + 31516297 = 31516304
  • 67 + 31516237 = 31516304
  • 103 + 31516201 = 31516304
  • 151 + 31516153 = 31516304
  • 181 + 31516123 = 31516304
  • 223 + 31516081 = 31516304
  • 277 + 31516027 = 31516304
  • 283 + 31516021 = 31516304

Showing the first eight; more decompositions exist.
