Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559416, here are decompositions:

3 + 31559413 = 31559416
197 + 31559219 = 31559416
227 + 31559189 = 31559416
347 + 31559069 = 31559416
389 + 31559027 = 31559416
419 + 31558997 = 31559416
443 + 31558973 = 31559416
557 + 31558859 = 31559416

Showing the first eight; more decompositions exist.
