Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566452, here are decompositions:

3 + 31566449 = 31566452
103 + 31566349 = 31566452
163 + 31566289 = 31566452
283 + 31566169 = 31566452
373 + 31566079 = 31566452
409 + 31566043 = 31566452
433 + 31566019 = 31566452
439 + 31566013 = 31566452

Showing the first eight; more decompositions exist.
