Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529582, here are decompositions:

31 + 31529551 = 31529582
43 + 31529539 = 31529582
61 + 31529521 = 31529582
103 + 31529479 = 31529582
151 + 31529431 = 31529582
223 + 31529359 = 31529582
229 + 31529353 = 31529582
313 + 31529269 = 31529582

Showing the first eight; more decompositions exist.
