Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559382, here are decompositions:

11 + 31559371 = 31559382
31 + 31559351 = 31559382
61 + 31559321 = 31559382
131 + 31559251 = 31559382
163 + 31559219 = 31559382
193 + 31559189 = 31559382
233 + 31559149 = 31559382
251 + 31559131 = 31559382

Showing the first eight; more decompositions exist.
