Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493280, here are decompositions:

3 + 493277 = 493280
31 + 493249 = 493280
37 + 493243 = 493280
61 + 493219 = 493280
79 + 493201 = 493280
103 + 493177 = 493280
157 + 493123 = 493280
313 + 492967 = 493280

Showing the first eight; more decompositions exist.
