Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529364, here are decompositions:

5 + 31529359 = 31529364
11 + 31529353 = 31529364
17 + 31529347 = 31529364
43 + 31529321 = 31529364
107 + 31529257 = 31529364
151 + 31529213 = 31529364
197 + 31529167 = 31529364
257 + 31529107 = 31529364

Showing the first eight; more decompositions exist.
