Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522266, here are decompositions:

19 + 31522247 = 31522266
23 + 31522243 = 31522266
37 + 31522229 = 31522266
47 + 31522219 = 31522266
59 + 31522207 = 31522266
137 + 31522129 = 31522266
163 + 31522103 = 31522266
313 + 31521953 = 31522266

Showing the first eight; more decompositions exist.
