Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494816, here are decompositions:

13 + 494803 = 494816
67 + 494749 = 494816
73 + 494743 = 494816
79 + 494737 = 494816
97 + 494719 = 494816
103 + 494713 = 494816
139 + 494677 = 494816
199 + 494617 = 494816

Showing the first eight; more decompositions exist.
