Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529406, here are decompositions:

47 + 31529359 = 31529406
53 + 31529353 = 31529406
59 + 31529347 = 31529406
127 + 31529279 = 31529406
137 + 31529269 = 31529406
149 + 31529257 = 31529406
157 + 31529249 = 31529406
163 + 31529243 = 31529406

Showing the first eight; more decompositions exist.
