Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494780, here are decompositions:

19 + 494761 = 494780
31 + 494749 = 494780
37 + 494743 = 494780
43 + 494737 = 494780
61 + 494719 = 494780
67 + 494713 = 494780
103 + 494677 = 494780
109 + 494671 = 494780

Showing the first eight; more decompositions exist.
