Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491338, here are decompositions:

5 + 491333 = 491338
11 + 491327 = 491338
41 + 491297 = 491338
59 + 491279 = 491338
137 + 491201 = 491338
167 + 491171 = 491338
179 + 491159 = 491338
257 + 491081 = 491338

Showing the first eight; more decompositions exist.
