Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565334, here are decompositions:

11 + 31565323 = 31565334
37 + 31565297 = 31565334
41 + 31565293 = 31565334
43 + 31565291 = 31565334
103 + 31565231 = 31565334
113 + 31565221 = 31565334
127 + 31565207 = 31565334
137 + 31565197 = 31565334

Showing the first eight; more decompositions exist.
