Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498400, here are decompositions:

  • 7 + 2147498393 = 2147498400
  • 13 + 2147498387 = 2147498400
  • 37 + 2147498363 = 2147498400
  • 53 + 2147498347 = 2147498400
  • 59 + 2147498341 = 2147498400
  • 67 + 2147498333 = 2147498400
  • 191 + 2147498209 = 2147498400
  • 211 + 2147498189 = 2147498400

Showing the first eight; more decompositions exist.
