Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497942, here are decompositions:

  • 3 + 2147497939 = 2147497942
  • 41 + 2147497901 = 2147497942
  • 53 + 2147497889 = 2147497942
  • 173 + 2147497769 = 2147497942
  • 251 + 2147497691 = 2147497942
  • 281 + 2147497661 = 2147497942
  • 383 + 2147497559 = 2147497942
  • 419 + 2147497523 = 2147497942

Showing the first eight; more decompositions exist.
