Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501786, here are decompositions:

  • 37 + 2147501749 = 2147501786
  • 103 + 2147501683 = 2147501786
  • 109 + 2147501677 = 2147501786
  • 163 + 2147501623 = 2147501786
  • 307 + 2147501479 = 2147501786
  • 349 + 2147501437 = 2147501786
  • 613 + 2147501173 = 2147501786
  • 643 + 2147501143 = 2147501786

Showing the first eight; more decompositions exist.
