Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586750, here are decompositions:

  • 7 + 2147586743 = 2147586750
  • 17 + 2147586733 = 2147586750
  • 19 + 2147586731 = 2147586750
  • 41 + 2147586709 = 2147586750
  • 47 + 2147586703 = 2147586750
  • 83 + 2147586667 = 2147586750
  • 97 + 2147586653 = 2147586750
  • 139 + 2147586611 = 2147586750

Showing the first eight; more decompositions exist.
