Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566344, here are decompositions:

97 + 31566247 = 31566344
193 + 31566151 = 31566344
283 + 31566061 = 31566344
331 + 31566013 = 31566344
373 + 31565971 = 31566344
457 + 31565887 = 31566344
541 + 31565803 = 31566344
631 + 31565713 = 31566344

Showing the first eight; more decompositions exist.
