Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565552, here are decompositions:

13 + 31565539 = 31565552
61 + 31565491 = 31565552
79 + 31565473 = 31565552
199 + 31565353 = 31565552
229 + 31565323 = 31565552
331 + 31565221 = 31565552
379 + 31565173 = 31565552
433 + 31565119 = 31565552

Showing the first eight; more decompositions exist.
