Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528244, here are decompositions:

3 + 31528241 = 31528244
31 + 31528213 = 31528244
37 + 31528207 = 31528244
73 + 31528171 = 31528244
151 + 31528093 = 31528244
277 + 31527967 = 31528244
313 + 31527931 = 31528244
331 + 31527913 = 31528244

Showing the first eight; more decompositions exist.
