Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494870, here are decompositions:

67 + 494803 = 494870
109 + 494761 = 494870
127 + 494743 = 494870
139 + 494731 = 494870
151 + 494719 = 494870
157 + 494713 = 494870
193 + 494677 = 494870
199 + 494671 = 494870

Showing the first eight; more decompositions exist.
