Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566174, here are decompositions:

5 + 31566169 = 31566174
7 + 31566167 = 31566174
23 + 31566151 = 31566174
37 + 31566137 = 31566174
43 + 31566131 = 31566174
97 + 31566077 = 31566174
113 + 31566061 = 31566174
131 + 31566043 = 31566174

Showing the first eight; more decompositions exist.
