Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500940, here are decompositions:

  • 3 + 2147500937 = 2147500940
  • 31 + 2147500909 = 2147500940
  • 61 + 2147500879 = 2147500940
  • 127 + 2147500813 = 2147500940
  • 313 + 2147500627 = 2147500940
  • 349 + 2147500591 = 2147500940
  • 379 + 2147500561 = 2147500940
  • 433 + 2147500507 = 2147500940

Showing the first eight; more decompositions exist.
