Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565262, here are decompositions:

5 + 31565257 = 31565262
13 + 31565249 = 31565262
31 + 31565231 = 31565262
41 + 31565221 = 31565262
89 + 31565173 = 31565262
103 + 31565159 = 31565262
193 + 31565069 = 31565262
233 + 31565029 = 31565262

Showing the first eight; more decompositions exist.
