Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489788, here are decompositions:

  • 71 + 2147489717 = 2147489788
  • 89 + 2147489699 = 2147489788
  • 137 + 2147489651 = 2147489788
  • 149 + 2147489639 = 2147489788
  • 251 + 2147489537 = 2147489788
  • 347 + 2147489441 = 2147489788
  • 491 + 2147489297 = 2147489788
  • 701 + 2147489087 = 2147489788

Showing the first eight; more decompositions exist.
