Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559446, here are decompositions:

3 + 31559443 = 31559446
29 + 31559417 = 31559446
227 + 31559219 = 31559446
239 + 31559207 = 31559446
257 + 31559189 = 31559446
353 + 31559093 = 31559446
419 + 31559027 = 31559446
449 + 31558997 = 31559446

Showing the first eight; more decompositions exist.
