Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469884, here are decompositions:

  • 3 + 2147469881 = 2147469884
  • 61 + 2147469823 = 2147469884
  • 67 + 2147469817 = 2147469884
  • 103 + 2147469781 = 2147469884
  • 181 + 2147469703 = 2147469884
  • 331 + 2147469553 = 2147469884
  • 421 + 2147469463 = 2147469884
  • 463 + 2147469421 = 2147469884

Showing the first eight; more decompositions exist.
