Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531596, here are decompositions:

17 + 31531579 = 31531596
73 + 31531523 = 31531596
113 + 31531483 = 31531596
139 + 31531457 = 31531596
179 + 31531417 = 31531596
193 + 31531403 = 31531596
197 + 31531399 = 31531596
227 + 31531369 = 31531596

Showing the first eight; more decompositions exist.
