Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147461222, here are decompositions:

  • 89 + 2147461133 = 2147461222
  • 239 + 2147460983 = 2147461222
  • 311 + 2147460911 = 2147461222
  • 353 + 2147460869 = 2147461222
  • 443 + 2147460779 = 2147461222
  • 449 + 2147460773 = 2147461222
  • 563 + 2147460659 = 2147461222
  • 593 + 2147460629 = 2147461222

Showing the first eight; more decompositions exist.
