Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491316, here are decompositions:

17 + 491299 = 491316
19 + 491297 = 491316
37 + 491279 = 491316
43 + 491273 = 491316
97 + 491219 = 491316
103 + 491213 = 491316
149 + 491167 = 491316
157 + 491159 = 491316

Showing the first eight; more decompositions exist.
