Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90494, here are decompositions:

13 + 90481 = 90494
97 + 90397 = 90494
181 + 90313 = 90494
223 + 90271 = 90494
277 + 90217 = 90494
307 + 90187 = 90494
331 + 90163 = 90494
367 + 90127 = 90494

Showing the first eight; more decompositions exist.
