Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90428, here are decompositions:

31 + 90397 = 90428
139 + 90289 = 90428
157 + 90271 = 90428
181 + 90247 = 90428
211 + 90217 = 90428
229 + 90199 = 90428
241 + 90187 = 90428
307 + 90121 = 90428

Showing the first eight; more decompositions exist.
