Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529366, here are decompositions:

7 + 31529359 = 31529366
13 + 31529353 = 31529366
19 + 31529347 = 31529366
97 + 31529269 = 31529366
109 + 31529257 = 31529366
199 + 31529167 = 31529366
277 + 31529089 = 31529366
313 + 31529053 = 31529366

Showing the first eight; more decompositions exist.
