Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566532, here are decompositions:

5 + 31566527 = 31566532
59 + 31566473 = 31566532
83 + 31566449 = 31566532
89 + 31566443 = 31566532
149 + 31566383 = 31566532
233 + 31566299 = 31566532
281 + 31566251 = 31566532
311 + 31566221 = 31566532

Showing the first eight; more decompositions exist.
