Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494660, here are decompositions:

13 + 494647 = 494660
43 + 494617 = 494660
73 + 494587 = 494660
97 + 494563 = 494660
139 + 494521 = 494660
163 + 494497 = 494660
277 + 494383 = 494660
307 + 494353 = 494660

Showing the first eight; more decompositions exist.
