Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489658, here are decompositions:

  • 5 + 2147489653 = 2147489658
  • 7 + 2147489651 = 2147489658
  • 19 + 2147489639 = 2147489658
  • 71 + 2147489587 = 2147489658
  • 79 + 2147489579 = 2147489658
  • 257 + 2147489401 = 2147489658
  • 311 + 2147489347 = 2147489658
  • 359 + 2147489299 = 2147489658

Showing the first eight; more decompositions exist.
