Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491368, here are decompositions:

11 + 491357 = 491368
29 + 491339 = 491368
41 + 491327 = 491368
71 + 491297 = 491368
89 + 491279 = 491368
107 + 491261 = 491368
149 + 491219 = 491368
167 + 491201 = 491368

Showing the first eight; more decompositions exist.
