Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528846, here are decompositions:

3 + 31528843 = 31528846
5 + 31528841 = 31528846
23 + 31528823 = 31528846
149 + 31528697 = 31528846
233 + 31528613 = 31528846
347 + 31528499 = 31528846
509 + 31528337 = 31528846
563 + 31528283 = 31528846

Showing the first eight; more decompositions exist.
