Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529600, here are decompositions:

7 + 31529593 = 31529600
43 + 31529557 = 31529600
61 + 31529539 = 31529600
79 + 31529521 = 31529600
241 + 31529359 = 31529600
331 + 31529269 = 31529600
433 + 31529167 = 31529600
547 + 31529053 = 31529600

Showing the first eight; more decompositions exist.
