Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559226, here are decompositions:

7 + 31559219 = 31559226
19 + 31559207 = 31559226
37 + 31559189 = 31559226
157 + 31559069 = 31559226
199 + 31559027 = 31559226
229 + 31558997 = 31559226
233 + 31558993 = 31559226
263 + 31558963 = 31559226

Showing the first eight; more decompositions exist.
