Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522204, here are decompositions:

23 + 31522181 = 31522204
101 + 31522103 = 31522204
113 + 31522091 = 31522204
191 + 31522013 = 31522204
227 + 31521977 = 31522204
251 + 31521953 = 31522204
317 + 31521887 = 31522204
353 + 31521851 = 31522204

Showing the first eight; more decompositions exist.
