Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619564, here are decompositions:

3 + 31619561 = 31619564
7 + 31619557 = 31619564
37 + 31619527 = 31619564
43 + 31619521 = 31619564
157 + 31619407 = 31619564
283 + 31619281 = 31619564
307 + 31619257 = 31619564
373 + 31619191 = 31619564

Showing the first eight; more decompositions exist.
