Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448746, here are decompositions:

  • 13 + 2147448733 = 2147448746
  • 43 + 2147448703 = 2147448746
  • 67 + 2147448679 = 2147448746
  • 337 + 2147448409 = 2147448746
  • 367 + 2147448379 = 2147448746
  • 379 + 2147448367 = 2147448746
  • 733 + 2147448013 = 2147448746
  • 769 + 2147447977 = 2147448746

Showing the first eight; more decompositions exist.
