Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147575844, here are decompositions:

  • 157 + 2147575687 = 2147575844
  • 367 + 2147575477 = 2147575844
  • 397 + 2147575447 = 2147575844
  • 607 + 2147575237 = 2147575844
  • 613 + 2147575231 = 2147575844
  • 937 + 2147574907 = 2147575844
  • 991 + 2147574853 = 2147575844
  • 1291 + 2147574553 = 2147575844

Showing the first eight; more decompositions exist.
