Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521596, here are decompositions:

3 + 31521593 = 31521596
37 + 31521559 = 31521596
97 + 31521499 = 31521596
157 + 31521439 = 31521596
163 + 31521433 = 31521596
367 + 31521229 = 31521596
373 + 31521223 = 31521596
439 + 31521157 = 31521596

Showing the first eight; more decompositions exist.
