Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489268, here are decompositions:

  • 5 + 2147489263 = 2147489268
  • 61 + 2147489207 = 2147489268
  • 179 + 2147489089 = 2147489268
  • 181 + 2147489087 = 2147489268
  • 191 + 2147489077 = 2147489268
  • 251 + 2147489017 = 2147489268
  • 271 + 2147488997 = 2147489268
  • 349 + 2147488919 = 2147489268

Showing the first eight; more decompositions exist.
