Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566314, here are decompositions:

67 + 31566247 = 31566314
163 + 31566151 = 31566314
271 + 31566043 = 31566314
313 + 31566001 = 31566314
397 + 31565917 = 31566314
463 + 31565851 = 31566314
523 + 31565791 = 31566314
601 + 31565713 = 31566314

Showing the first eight; more decompositions exist.
