Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532566, here are decompositions:

59 + 31532507 = 31532566
89 + 31532477 = 31532566
137 + 31532429 = 31532566
227 + 31532339 = 31532566
347 + 31532219 = 31532566
449 + 31532117 = 31532566
503 + 31532063 = 31532566
563 + 31532003 = 31532566

Showing the first eight; more decompositions exist.
