Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559774, here are decompositions:

3 + 31559771 = 31559774
97 + 31559677 = 31559774
151 + 31559623 = 31559774
307 + 31559467 = 31559774
331 + 31559443 = 31559774
373 + 31559401 = 31559774
457 + 31559317 = 31559774
523 + 31559251 = 31559774

Showing the first eight; more decompositions exist.
