Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559674, here are decompositions:

23 + 31559651 = 31559674
101 + 31559573 = 31559674
137 + 31559537 = 31559674
173 + 31559501 = 31559674
227 + 31559447 = 31559674
257 + 31559417 = 31559674
353 + 31559321 = 31559674
467 + 31559207 = 31559674

Showing the first eight; more decompositions exist.
