Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147509844, here are decompositions:

  • 223 + 2147509621 = 2147509844
  • 421 + 2147509423 = 2147509844
  • 523 + 2147509321 = 2147509844
  • 547 + 2147509297 = 2147509844
  • 661 + 2147509183 = 2147509844
  • 937 + 2147508907 = 2147509844
  • 1051 + 2147508793 = 2147509844
  • 1093 + 2147508751 = 2147509844

Showing the first eight; more decompositions exist.
