Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529546, here are decompositions:

7 + 31529539 = 31529546
67 + 31529479 = 31529546
193 + 31529353 = 31529546
199 + 31529347 = 31529546
277 + 31529269 = 31529546
379 + 31529167 = 31529546
397 + 31529149 = 31529546
439 + 31529107 = 31529546

Showing the first eight; more decompositions exist.
