Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497234, here are decompositions:

  • 101 + 2147497133 = 2147497234
  • 191 + 2147497043 = 2147497234
  • 263 + 2147496971 = 2147497234
  • 293 + 2147496941 = 2147497234
  • 317 + 2147496917 = 2147497234
  • 503 + 2147496731 = 2147497234
  • 521 + 2147496713 = 2147497234
  • 677 + 2147496557 = 2147497234

Showing the first eight; more decompositions exist.
