Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147547822, here are decompositions:

  • 31 + 2147547791 = 2147547822
  • 83 + 2147547739 = 2147547822
  • 151 + 2147547671 = 2147547822
  • 311 + 2147547511 = 2147547822
  • 359 + 2147547463 = 2147547822
  • 419 + 2147547403 = 2147547822
  • 421 + 2147547401 = 2147547822
  • 439 + 2147547383 = 2147547822

Showing the first eight; more decompositions exist.
