Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468394, here are decompositions:

  • 53 + 2147468341 = 2147468394
  • 103 + 2147468291 = 2147468394
  • 163 + 2147468231 = 2147468394
  • 263 + 2147468131 = 2147468394
  • 431 + 2147467963 = 2147468394
  • 523 + 2147467871 = 2147468394
  • 593 + 2147467801 = 2147468394
  • 601 + 2147467793 = 2147468394

Showing the first eight; more decompositions exist.
