Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489642, here are decompositions:

  • 3 + 2147489639 = 2147489642
  • 139 + 2147489503 = 2147489642
  • 241 + 2147489401 = 2147489642
  • 379 + 2147489263 = 2147489642
  • 439 + 2147489203 = 2147489642
  • 499 + 2147489143 = 2147489642
  • 619 + 2147489023 = 2147489642
  • 1063 + 2147488579 = 2147489642

Showing the first eight; more decompositions exist.
