Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597076, here are decompositions:

73 + 31597003 = 31597076
79 + 31596997 = 31597076
127 + 31596949 = 31597076
163 + 31596913 = 31597076
193 + 31596883 = 31597076
229 + 31596847 = 31597076
283 + 31596793 = 31597076
307 + 31596769 = 31597076

Showing the first eight; more decompositions exist.
