Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492830, here are decompositions:

31 + 492799 = 492830
61 + 492769 = 492830
67 + 492763 = 492830
73 + 492757 = 492830
109 + 492721 = 492830
157 + 492673 = 492830
199 + 492631 = 492830
211 + 492619 = 492830

Showing the first eight; more decompositions exist.
