Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468378, here are decompositions:

  • 37 + 2147468341 = 2147468378
  • 61 + 2147468317 = 2147468378
  • 109 + 2147468269 = 2147468378
  • 457 + 2147467921 = 2147468378
  • 577 + 2147467801 = 2147468378
  • 619 + 2147467759 = 2147468378
  • 631 + 2147467747 = 2147468378
  • 661 + 2147467717 = 2147468378

Showing the first eight; more decompositions exist.
