Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90278, here are decompositions:

7 + 90271 = 90278
31 + 90247 = 90278
61 + 90217 = 90278
79 + 90199 = 90278
151 + 90127 = 90278
157 + 90121 = 90278
211 + 90067 = 90278
271 + 90007 = 90278

Showing the first eight; more decompositions exist.
