Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566524, here are decompositions:

7 + 31566517 = 31566524
37 + 31566487 = 31566524
43 + 31566481 = 31566524
97 + 31566427 = 31566524
127 + 31566397 = 31566524
277 + 31566247 = 31566524
373 + 31566151 = 31566524
463 + 31566061 = 31566524

Showing the first eight; more decompositions exist.
