Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494100, here are decompositions:

7 + 494093 = 494100
17 + 494083 = 494100
23 + 494077 = 494100
31 + 494069 = 494100
59 + 494041 = 494100
71 + 494029 = 494100
107 + 493993 = 494100
127 + 493973 = 494100

Showing the first eight; more decompositions exist.
