Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497272, here are decompositions:

  • 29 + 2147497243 = 2147497272
  • 71 + 2147497201 = 2147497272
  • 131 + 2147497141 = 2147497272
  • 139 + 2147497133 = 2147497272
  • 191 + 2147497081 = 2147497272
  • 229 + 2147497043 = 2147497272
  • 233 + 2147497039 = 2147497272
  • 293 + 2147496979 = 2147497272

Showing the first eight; more decompositions exist.
