Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529224, here are decompositions:

5 + 31529219 = 31529224
11 + 31529213 = 31529224
137 + 31529087 = 31529224
227 + 31528997 = 31529224
257 + 31528967 = 31529224
383 + 31528841 = 31529224
401 + 31528823 = 31529224
677 + 31528547 = 31529224

Showing the first eight; more decompositions exist.
