Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494244, here are decompositions:

7 + 494237 = 494244
31 + 494213 = 494244
53 + 494191 = 494244
97 + 494147 = 494244
103 + 494141 = 494244
137 + 494107 = 494244
151 + 494093 = 494244
167 + 494077 = 494244

Showing the first eight; more decompositions exist.
