Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426144, here are decompositions:

  • 7 + 2147426137 = 2147426144
  • 37 + 2147426107 = 2147426144
  • 151 + 2147425993 = 2147426144
  • 211 + 2147425933 = 2147426144
  • 433 + 2147425711 = 2147426144
  • 463 + 2147425681 = 2147426144
  • 613 + 2147425531 = 2147426144
  • 631 + 2147425513 = 2147426144

Showing the first eight; more decompositions exist.
