Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467398, here are decompositions:

  • 5 + 2147467393 = 2147467398
  • 19 + 2147467379 = 2147467398
  • 31 + 2147467367 = 2147467398
  • 59 + 2147467339 = 2147467398
  • 67 + 2147467331 = 2147467398
  • 71 + 2147467327 = 2147467398
  • 137 + 2147467261 = 2147467398
  • 179 + 2147467219 = 2147467398

Showing the first eight; more decompositions exist.
