Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485268, here are decompositions:

  • 7 + 2147485261 = 2147485268
  • 67 + 2147485201 = 2147485268
  • 79 + 2147485189 = 2147485268
  • 127 + 2147485141 = 2147485268
  • 211 + 2147485057 = 2147485268
  • 277 + 2147484991 = 2147485268
  • 307 + 2147484961 = 2147485268
  • 349 + 2147484919 = 2147485268

Showing the first eight; more decompositions exist.
