Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494810, here are decompositions:

7 + 494803 = 494810
61 + 494749 = 494810
67 + 494743 = 494810
73 + 494737 = 494810
79 + 494731 = 494810
97 + 494713 = 494810
139 + 494671 = 494810
163 + 494647 = 494810

Showing the first eight; more decompositions exist.
