Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566582, here are decompositions:

23 + 31566559 = 31566582
41 + 31566541 = 31566582
59 + 31566523 = 31566582
101 + 31566481 = 31566582
109 + 31566473 = 31566582
139 + 31566443 = 31566582
193 + 31566389 = 31566582
199 + 31566383 = 31566582

Showing the first eight; more decompositions exist.
