Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498744, here are decompositions:

  • 3 + 2147498741 = 2147498744
  • 7 + 2147498737 = 2147498744
  • 67 + 2147498677 = 2147498744
  • 151 + 2147498593 = 2147498744
  • 163 + 2147498581 = 2147498744
  • 331 + 2147498413 = 2147498744
  • 397 + 2147498347 = 2147498744
  • 823 + 2147497921 = 2147498744

Showing the first eight; more decompositions exist.
