Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491194, here are decompositions:

23 + 491171 = 491194
113 + 491081 = 491194
191 + 491003 = 491194
227 + 490967 = 491194
257 + 490937 = 491194
281 + 490913 = 491194
317 + 490877 = 491194
461 + 490733 = 491194

Showing the first eight; more decompositions exist.
