Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494148, here are decompositions:

7 + 494141 = 494148
19 + 494129 = 494148
41 + 494107 = 494148
47 + 494101 = 494148
71 + 494077 = 494148
79 + 494069 = 494148
97 + 494051 = 494148
107 + 494041 = 494148

Showing the first eight; more decompositions exist.
