Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597556, here are decompositions:

7 + 31597549 = 31597556
73 + 31597483 = 31597556
103 + 31597453 = 31597556
139 + 31597417 = 31597556
313 + 31597243 = 31597556
379 + 31597177 = 31597556
457 + 31597099 = 31597556
607 + 31596949 = 31597556

Showing the first eight; more decompositions exist.
