Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90728, here are decompositions:

19 + 90709 = 90728
31 + 90697 = 90728
97 + 90631 = 90728
109 + 90619 = 90728
181 + 90547 = 90728
199 + 90529 = 90728
229 + 90499 = 90728
331 + 90397 = 90728

Showing the first eight; more decompositions exist.
