Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565276, here are decompositions:

19 + 31565257 = 31565276
79 + 31565197 = 31565276
103 + 31565173 = 31565276
109 + 31565167 = 31565276
157 + 31565119 = 31565276
199 + 31565077 = 31565276
229 + 31565047 = 31565276
349 + 31564927 = 31565276

Showing the first eight; more decompositions exist.
