Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466940, here are decompositions:

  • 71 + 2147466869 = 2147466940
  • 107 + 2147466833 = 2147466940
  • 239 + 2147466701 = 2147466940
  • 257 + 2147466683 = 2147466940
  • 401 + 2147466539 = 2147466940
  • 419 + 2147466521 = 2147466940
  • 461 + 2147466479 = 2147466940
  • 491 + 2147466449 = 2147466940

Showing the first eight; more decompositions exist.
