Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494190, here are decompositions:

23 + 494167 = 494190
43 + 494147 = 494190
61 + 494129 = 494190
83 + 494107 = 494190
89 + 494101 = 494190
97 + 494093 = 494190
107 + 494083 = 494190
113 + 494077 = 494190

Showing the first eight; more decompositions exist.
