Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494142, here are decompositions:

13 + 494129 = 494142
41 + 494101 = 494142
59 + 494083 = 494142
73 + 494069 = 494142
101 + 494041 = 494142
113 + 494029 = 494142
149 + 493993 = 494142
163 + 493979 = 494142

Showing the first eight; more decompositions exist.
