Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424338, here are decompositions:

  • 79 + 2147424259 = 2147424338
  • 211 + 2147424127 = 2147424338
  • 331 + 2147424007 = 2147424338
  • 379 + 2147423959 = 2147424338
  • 421 + 2147423917 = 2147424338
  • 457 + 2147423881 = 2147424338
  • 487 + 2147423851 = 2147424338
  • 691 + 2147423647 = 2147424338

Showing the first eight; more decompositions exist.
