Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494678, here are decompositions:

7 + 494671 = 494678
31 + 494647 = 494678
61 + 494617 = 494678
139 + 494539 = 494678
157 + 494521 = 494678
181 + 494497 = 494678
271 + 494407 = 494678
337 + 494341 = 494678

Showing the first eight; more decompositions exist.
