Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584376, here are decompositions:

  • 127 + 2147584249 = 2147584376
  • 307 + 2147584069 = 2147584376
  • 313 + 2147584063 = 2147584376
  • 409 + 2147583967 = 2147584376
  • 433 + 2147583943 = 2147584376
  • 439 + 2147583937 = 2147584376
  • 547 + 2147583829 = 2147584376
  • 577 + 2147583799 = 2147584376

Showing the first eight; more decompositions exist.
