Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586740, here are decompositions:

  • 7 + 2147586733 = 2147586740
  • 31 + 2147586709 = 2147586740
  • 37 + 2147586703 = 2147586740
  • 73 + 2147586667 = 2147586740
  • 151 + 2147586589 = 2147586740
  • 193 + 2147586547 = 2147586740
  • 283 + 2147586457 = 2147586740
  • 379 + 2147586361 = 2147586740

Showing the first eight; more decompositions exist.
