Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422922, here are decompositions:

  • 31 + 2147422891 = 2147422922
  • 61 + 2147422861 = 2147422922
  • 103 + 2147422819 = 2147422922
  • 199 + 2147422723 = 2147422922
  • 349 + 2147422573 = 2147422922
  • 373 + 2147422549 = 2147422922
  • 433 + 2147422489 = 2147422922
  • 709 + 2147422213 = 2147422922

Showing the first eight; more decompositions exist.
