Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448178, here are decompositions:

  • 107 + 2147448071 = 2147448178
  • 191 + 2147447987 = 2147448178
  • 401 + 2147447777 = 2147448178
  • 431 + 2147447747 = 2147448178
  • 509 + 2147447669 = 2147448178
  • 521 + 2147447657 = 2147448178
  • 569 + 2147447609 = 2147448178
  • 719 + 2147447459 = 2147448178

Showing the first eight; more decompositions exist.
