Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566362, here are decompositions:

13 + 31566349 = 31566362
73 + 31566289 = 31566362
193 + 31566169 = 31566362
211 + 31566151 = 31566362
283 + 31566079 = 31566362
349 + 31566013 = 31566362
409 + 31565953 = 31566362
433 + 31565929 = 31566362

Showing the first eight; more decompositions exist.
