Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497954, here are decompositions:

  • 5 + 2147497949 = 2147497954
  • 11 + 2147497943 = 2147497954
  • 47 + 2147497907 = 2147497954
  • 53 + 2147497901 = 2147497954
  • 197 + 2147497757 = 2147497954
  • 257 + 2147497697 = 2147497954
  • 263 + 2147497691 = 2147497954
  • 293 + 2147497661 = 2147497954

Showing the first eight; more decompositions exist.
