Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615596, here are decompositions:

7 + 31615589 = 31615596
13 + 31615583 = 31615596
53 + 31615543 = 31615596
107 + 31615489 = 31615596
113 + 31615483 = 31615596
157 + 31615439 = 31615596
167 + 31615429 = 31615596
179 + 31615417 = 31615596

Showing the first eight; more decompositions exist.
