Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584394, here are decompositions:

  • 3 + 2147584391 = 2147584394
  • 73 + 2147584321 = 2147584394
  • 271 + 2147584123 = 2147584394
  • 331 + 2147584063 = 2147584394
  • 337 + 2147584057 = 2147584394
  • 433 + 2147583961 = 2147584394
  • 457 + 2147583937 = 2147584394
  • 601 + 2147583793 = 2147584394

Showing the first eight; more decompositions exist.
