Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597754, here are decompositions:

37 + 31597717 = 31597754
61 + 31597693 = 31597754
103 + 31597651 = 31597754
151 + 31597603 = 31597754
271 + 31597483 = 31597754
283 + 31597471 = 31597754
337 + 31597417 = 31597754
523 + 31597231 = 31597754

Showing the first eight; more decompositions exist.
