Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494178, here are decompositions:

11 + 494167 = 494178
31 + 494147 = 494178
37 + 494141 = 494178
71 + 494107 = 494178
101 + 494077 = 494178
109 + 494069 = 494178
127 + 494051 = 494178
137 + 494041 = 494178

Showing the first eight; more decompositions exist.
