Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498544, here are decompositions:

  • 43 + 2147498501 = 2147498544
  • 73 + 2147498471 = 2147498544
  • 131 + 2147498413 = 2147498544
  • 151 + 2147498393 = 2147498544
  • 157 + 2147498387 = 2147498544
  • 181 + 2147498363 = 2147498544
  • 197 + 2147498347 = 2147498544
  • 211 + 2147498333 = 2147498544

Showing the first eight; more decompositions exist.
