Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435798, here are decompositions:

  • 7 + 2147435791 = 2147435798
  • 61 + 2147435737 = 2147435798
  • 97 + 2147435701 = 2147435798
  • 199 + 2147435599 = 2147435798
  • 229 + 2147435569 = 2147435798
  • 271 + 2147435527 = 2147435798
  • 307 + 2147435491 = 2147435798
  • 367 + 2147435431 = 2147435798

Showing the first eight; more decompositions exist.
