Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491286, here are decompositions:

7 + 491279 = 491286
13 + 491273 = 491286
67 + 491219 = 491286
73 + 491213 = 491286
127 + 491159 = 491286
137 + 491149 = 491286
149 + 491137 = 491286
157 + 491129 = 491286

Showing the first eight; more decompositions exist.
