Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468408, here are decompositions:

  • 67 + 2147468341 = 2147468408
  • 139 + 2147468269 = 2147468408
  • 277 + 2147468131 = 2147468408
  • 487 + 2147467921 = 2147468408
  • 607 + 2147467801 = 2147468408
  • 661 + 2147467747 = 2147468408
  • 691 + 2147467717 = 2147468408
  • 739 + 2147467669 = 2147468408

Showing the first eight; more decompositions exist.
