Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494180, here are decompositions:

13 + 494167 = 494180
73 + 494107 = 494180
79 + 494101 = 494180
97 + 494083 = 494180
103 + 494077 = 494180
139 + 494041 = 494180
151 + 494029 = 494180
157 + 494023 = 494180

Showing the first eight; more decompositions exist.
