Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494942, here are decompositions:

3 + 494939 = 494942
43 + 494899 = 494942
139 + 494803 = 494942
181 + 494761 = 494942
193 + 494749 = 494942
199 + 494743 = 494942
211 + 494731 = 494942
223 + 494719 = 494942

Showing the first eight; more decompositions exist.
