Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456012, here are decompositions:

  • 19 + 2147455993 = 2147456012
  • 43 + 2147455969 = 2147456012
  • 109 + 2147455903 = 2147456012
  • 181 + 2147455831 = 2147456012
  • 271 + 2147455741 = 2147456012
  • 313 + 2147455699 = 2147456012
  • 349 + 2147455663 = 2147456012
  • 409 + 2147455603 = 2147456012

Showing the first eight; more decompositions exist.
