Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147545118, here are decompositions:

  • 79 + 2147545039 = 2147545118
  • 151 + 2147544967 = 2147545118
  • 241 + 2147544877 = 2147545118
  • 709 + 2147544409 = 2147545118
  • 811 + 2147544307 = 2147545118
  • 919 + 2147544199 = 2147545118
  • 1021 + 2147544097 = 2147545118
  • 1087 + 2147544031 = 2147545118

Showing the first eight; more decompositions exist.
