Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491310, here are decompositions:

11 + 491299 = 491310
13 + 491297 = 491310
31 + 491279 = 491310
37 + 491273 = 491310
59 + 491251 = 491310
97 + 491213 = 491310
109 + 491201 = 491310
139 + 491171 = 491310

Showing the first eight; more decompositions exist.
