Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147581952, here are decompositions:

  • 13 + 2147581939 = 2147581952
  • 349 + 2147581603 = 2147581952
  • 613 + 2147581339 = 2147581952
  • 619 + 2147581333 = 2147581952
  • 643 + 2147581309 = 2147581952
  • 709 + 2147581243 = 2147581952
  • 751 + 2147581201 = 2147581952
  • 823 + 2147581129 = 2147581952

Showing the first eight; more decompositions exist.
