Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494900, here are decompositions:

97 + 494803 = 494900
139 + 494761 = 494900
151 + 494749 = 494900
157 + 494743 = 494900
163 + 494737 = 494900
181 + 494719 = 494900
223 + 494677 = 494900
229 + 494671 = 494900

Showing the first eight; more decompositions exist.
