Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559374, here are decompositions:

3 + 31559371 = 31559374
23 + 31559351 = 31559374
53 + 31559321 = 31559374
167 + 31559207 = 31559374
281 + 31559093 = 31559374
293 + 31559081 = 31559374
347 + 31559027 = 31559374
401 + 31558973 = 31559374

Showing the first eight; more decompositions exist.
