Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404942, here are decompositions:

  • 41 + 2147404901 = 2147404942
  • 83 + 2147404859 = 2147404942
  • 101 + 2147404841 = 2147404942
  • 113 + 2147404829 = 2147404942
  • 359 + 2147404583 = 2147404942
  • 503 + 2147404439 = 2147404942
  • 593 + 2147404349 = 2147404942
  • 821 + 2147404121 = 2147404942

Showing the first eight; more decompositions exist.
