Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491116, here are decompositions:

113 + 491003 = 491116
149 + 490967 = 491116
167 + 490949 = 491116
179 + 490937 = 491116
239 + 490877 = 491116
257 + 490859 = 491116
347 + 490769 = 491116
383 + 490733 = 491116

Showing the first eight; more decompositions exist.
