Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566634, here are decompositions:

3 + 31566631 = 31566634
23 + 31566611 = 31566634
107 + 31566527 = 31566634
137 + 31566497 = 31566634
191 + 31566443 = 31566634
251 + 31566383 = 31566634
257 + 31566377 = 31566634
317 + 31566317 = 31566634

Showing the first eight; more decompositions exist.
