Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559596, here are decompositions:

23 + 31559573 = 31559596
59 + 31559537 = 31559596
149 + 31559447 = 31559596
179 + 31559417 = 31559596
389 + 31559207 = 31559596
503 + 31559093 = 31559596
569 + 31559027 = 31559596
599 + 31558997 = 31559596

Showing the first eight; more decompositions exist.
