Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494894, here are decompositions:

151 + 494743 = 494894
157 + 494737 = 494894
163 + 494731 = 494894
181 + 494713 = 494894
223 + 494671 = 494894
277 + 494617 = 494894
307 + 494587 = 494894
331 + 494563 = 494894

Showing the first eight; more decompositions exist.
