Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491326, here are decompositions:

29 + 491297 = 491326
47 + 491279 = 491326
53 + 491273 = 491326
107 + 491219 = 491326
113 + 491213 = 491326
167 + 491159 = 491326
197 + 491129 = 491326
359 + 490967 = 491326

Showing the first eight; more decompositions exist.
