Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565354, here are decompositions:

3 + 31565351 = 31565354
31 + 31565323 = 31565354
61 + 31565293 = 31565354
97 + 31565257 = 31565354
157 + 31565197 = 31565354
181 + 31565173 = 31565354
277 + 31565077 = 31565354
307 + 31565047 = 31565354

Showing the first eight; more decompositions exist.
