Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422018, here are decompositions:

  • 29 + 2147421989 = 2147422018
  • 107 + 2147421911 = 2147422018
  • 281 + 2147421737 = 2147422018
  • 491 + 2147421527 = 2147422018
  • 557 + 2147421461 = 2147422018
  • 569 + 2147421449 = 2147422018
  • 809 + 2147421209 = 2147422018
  • 839 + 2147421179 = 2147422018

Showing the first eight; more decompositions exist.
