Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529442, here are decompositions:

11 + 31529431 = 31529442
29 + 31529413 = 31529442
83 + 31529359 = 31529442
89 + 31529353 = 31529442
163 + 31529279 = 31529442
173 + 31529269 = 31529442
193 + 31529249 = 31529442
199 + 31529243 = 31529442

Showing the first eight; more decompositions exist.
