Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566088, here are decompositions:

5 + 31566083 = 31566088
11 + 31566077 = 31566088
107 + 31565981 = 31566088
317 + 31565771 = 31566088
677 + 31565411 = 31566088
797 + 31565291 = 31566088
809 + 31565279 = 31566088
839 + 31565249 = 31566088

Showing the first eight; more decompositions exist.
