Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528304, here are decompositions:

13 + 31528291 = 31528304
37 + 31528267 = 31528304
97 + 31528207 = 31528304
193 + 31528111 = 31528304
211 + 31528093 = 31528304
307 + 31527997 = 31528304
337 + 31527967 = 31528304
373 + 31527931 = 31528304

Showing the first eight; more decompositions exist.
