Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566374, here are decompositions:

127 + 31566247 = 31566374
223 + 31566151 = 31566374
313 + 31566061 = 31566374
331 + 31566043 = 31566374
373 + 31566001 = 31566374
421 + 31565953 = 31566374
457 + 31565917 = 31566374
487 + 31565887 = 31566374

Showing the first eight; more decompositions exist.
