Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529352, here are decompositions:

5 + 31529347 = 31529352
31 + 31529321 = 31529352
73 + 31529279 = 31529352
79 + 31529273 = 31529352
83 + 31529269 = 31529352
103 + 31529249 = 31529352
109 + 31529243 = 31529352
139 + 31529213 = 31529352

Showing the first eight; more decompositions exist.
