Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529394, here are decompositions:

41 + 31529353 = 31529394
47 + 31529347 = 31529394
73 + 31529321 = 31529394
137 + 31529257 = 31529394
151 + 31529243 = 31529394
181 + 31529213 = 31529394
227 + 31529167 = 31529394
307 + 31529087 = 31529394

Showing the first eight; more decompositions exist.
