Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527518, here are decompositions:

  • 19 + 31527499 = 31527518
  • 37 + 31527481 = 31527518
  • 241 + 31527277 = 31527518
  • 271 + 31527247 = 31527518
  • 307 + 31527211 = 31527518
  • 367 + 31527151 = 31527518
  • 409 + 31527109 = 31527518
  • 577 + 31526941 = 31527518

Showing the first eight; more decompositions exist.
