Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494280, here are decompositions:

11 + 494269 = 494280
13 + 494267 = 494280
23 + 494257 = 494280
29 + 494251 = 494280
43 + 494237 = 494280
67 + 494213 = 494280
89 + 494191 = 494280
113 + 494167 = 494280

Showing the first eight; more decompositions exist.
