Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147555612, here are decompositions:

  • 31 + 2147555581 = 2147555612
  • 61 + 2147555551 = 2147555612
  • 73 + 2147555539 = 2147555612
  • 79 + 2147555533 = 2147555612
  • 151 + 2147555461 = 2147555612
  • 283 + 2147555329 = 2147555612
  • 379 + 2147555233 = 2147555612
  • 421 + 2147555191 = 2147555612

Showing the first eight; more decompositions exist.
