Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147545924, here are decompositions:

  • 5 + 2147545919 = 2147545924
  • 71 + 2147545853 = 2147545924
  • 107 + 2147545817 = 2147545924
  • 317 + 2147545607 = 2147545924
  • 443 + 2147545481 = 2147545924
  • 647 + 2147545277 = 2147545924
  • 701 + 2147545223 = 2147545924
  • 773 + 2147545151 = 2147545924

Showing the first eight; more decompositions exist.
