Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494690, here are decompositions:

3 + 494687 = 494690
13 + 494677 = 494690
19 + 494671 = 494690
43 + 494647 = 494690
73 + 494617 = 494690
103 + 494587 = 494690
127 + 494563 = 494690
151 + 494539 = 494690

Showing the first eight; more decompositions exist.
