Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492778, here are decompositions:

17 + 492761 = 492778
47 + 492731 = 492778
59 + 492719 = 492778
71 + 492707 = 492778
107 + 492671 = 492778
131 + 492647 = 492778
137 + 492641 = 492778
149 + 492629 = 492778

Showing the first eight; more decompositions exist.
