Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529020, here are decompositions:

23 + 31528997 = 31529020
53 + 31528967 = 31529020
167 + 31528853 = 31529020
179 + 31528841 = 31529020
197 + 31528823 = 31529020
269 + 31528751 = 31529020
461 + 31528559 = 31529020
521 + 31528499 = 31529020

Showing the first eight; more decompositions exist.
