Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494786, here are decompositions:

3 + 494783 = 494786
37 + 494749 = 494786
43 + 494743 = 494786
67 + 494719 = 494786
73 + 494713 = 494786
109 + 494677 = 494786
139 + 494647 = 494786
199 + 494587 = 494786

Showing the first eight; more decompositions exist.
