Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492870, here are decompositions:

17 + 492853 = 492870
31 + 492839 = 492870
71 + 492799 = 492870
89 + 492781 = 492870
101 + 492769 = 492870
107 + 492763 = 492870
109 + 492761 = 492870
113 + 492757 = 492870

Showing the first eight; more decompositions exist.
