Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448016, here are decompositions:

  • 3 + 2147448013 = 2147448016
  • 29 + 2147447987 = 2147448016
  • 83 + 2147447933 = 2147448016
  • 239 + 2147447777 = 2147448016
  • 269 + 2147447747 = 2147448016
  • 293 + 2147447723 = 2147448016
  • 347 + 2147447669 = 2147448016
  • 359 + 2147447657 = 2147448016

Showing the first eight; more decompositions exist.
