Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494720, here are decompositions:

7 + 494713 = 494720
43 + 494677 = 494720
73 + 494647 = 494720
103 + 494617 = 494720
157 + 494563 = 494720
181 + 494539 = 494720
199 + 494521 = 494720
223 + 494497 = 494720

Showing the first eight; more decompositions exist.
