Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494840, here are decompositions:

37 + 494803 = 494840
79 + 494761 = 494840
97 + 494743 = 494840
103 + 494737 = 494840
109 + 494731 = 494840
127 + 494713 = 494840
163 + 494677 = 494840
193 + 494647 = 494840

Showing the first eight; more decompositions exist.
