Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528478, here are decompositions:

19 + 31528459 = 31528478
31 + 31528447 = 31528478
151 + 31528327 = 31528478
199 + 31528279 = 31528478
211 + 31528267 = 31528478
271 + 31528207 = 31528478
307 + 31528171 = 31528478
367 + 31528111 = 31528478

Showing the first eight; more decompositions exist.
