Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491350, here are decompositions:

11 + 491339 = 491350
17 + 491333 = 491350
23 + 491327 = 491350
53 + 491297 = 491350
71 + 491279 = 491350
89 + 491261 = 491350
131 + 491219 = 491350
137 + 491213 = 491350

Showing the first eight; more decompositions exist.
