Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147461816, here are decompositions:

  • 23 + 2147461793 = 2147461816
  • 29 + 2147461787 = 2147461816
  • 89 + 2147461727 = 2147461816
  • 197 + 2147461619 = 2147461816
  • 257 + 2147461559 = 2147461816
  • 317 + 2147461499 = 2147461816
  • 503 + 2147461313 = 2147461816
  • 659 + 2147461157 = 2147461816

Showing the first eight; more decompositions exist.
