Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478560, here are decompositions:

  • 43 + 2147478517 = 2147478560
  • 79 + 2147478481 = 2147478560
  • 211 + 2147478349 = 2147478560
  • 229 + 2147478331 = 2147478560
  • 307 + 2147478253 = 2147478560
  • 433 + 2147478127 = 2147478560
  • 547 + 2147478013 = 2147478560
  • 571 + 2147477989 = 2147478560

Showing the first eight; more decompositions exist.
