Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529510, here are decompositions:

3 + 31529507 = 31529510
31 + 31529479 = 31529510
79 + 31529431 = 31529510
97 + 31529413 = 31529510
151 + 31529359 = 31529510
157 + 31529353 = 31529510
163 + 31529347 = 31529510
241 + 31529269 = 31529510

Showing the first eight; more decompositions exist.
