Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483780, here are decompositions:

  • 3 + 2147483777 = 2147483780
  • 37 + 2147483743 = 2147483780
  • 67 + 2147483713 = 2147483780
  • 151 + 2147483629 = 2147483780
  • 193 + 2147483587 = 2147483780
  • 283 + 2147483497 = 2147483780
  • 457 + 2147483323 = 2147483780
  • 601 + 2147483179 = 2147483780

Showing the first eight; more decompositions exist.
