Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429044, here are decompositions:

  • 41 + 2147429003 = 2147429044
  • 53 + 2147428991 = 2147429044
  • 251 + 2147428793 = 2147429044
  • 317 + 2147428727 = 2147429044
  • 521 + 2147428523 = 2147429044
  • 641 + 2147428403 = 2147429044
  • 701 + 2147428343 = 2147429044
  • 863 + 2147428181 = 2147429044

Showing the first eight; more decompositions exist.
