Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494864, here are decompositions:

61 + 494803 = 494864
103 + 494761 = 494864
127 + 494737 = 494864
151 + 494713 = 494864
193 + 494671 = 494864
277 + 494587 = 494864
367 + 494497 = 494864
421 + 494443 = 494864

Showing the first eight; more decompositions exist.
