Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498440, here are decompositions:

  • 41 + 2147498399 = 2147498440
  • 47 + 2147498393 = 2147498440
  • 53 + 2147498387 = 2147498440
  • 107 + 2147498333 = 2147498440
  • 251 + 2147498189 = 2147498440
  • 293 + 2147498147 = 2147498440
  • 491 + 2147497949 = 2147498440
  • 683 + 2147497757 = 2147498440

Showing the first eight; more decompositions exist.
