Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597544, here are decompositions:

3 + 31597541 = 31597544
37 + 31597507 = 31597544
61 + 31597483 = 31597544
73 + 31597471 = 31597544
127 + 31597417 = 31597544
283 + 31597261 = 31597544
313 + 31597231 = 31597544
331 + 31597213 = 31597544

Showing the first eight; more decompositions exist.
