Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491190, here are decompositions:

19 + 491171 = 491190
23 + 491167 = 491190
31 + 491159 = 491190
41 + 491149 = 491190
53 + 491137 = 491190
61 + 491129 = 491190
107 + 491083 = 491190
109 + 491081 = 491190

Showing the first eight; more decompositions exist.
