Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597364, here are decompositions:

  • 103 + 31597261 = 31597364
  • 151 + 31597213 = 31597364
  • 283 + 31597081 = 31597364
  • 313 + 31597051 = 31597364
  • 367 + 31596997 = 31597364
  • 373 + 31596991 = 31597364
  • 457 + 31596907 = 31597364
  • 571 + 31596793 = 31597364

Showing the first eight; more decompositions exist.
