Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627472, here are decompositions:

  • 61 + 31627411 = 31627472
  • 139 + 31627333 = 31627472
  • 211 + 31627261 = 31627472
  • 223 + 31627249 = 31627472
  • 229 + 31627243 = 31627472
  • 271 + 31627201 = 31627472
  • 421 + 31627051 = 31627472
  • 439 + 31627033 = 31627472

Showing the first eight; more decompositions exist.
