Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942818, here are decompositions:

7 + 942811 = 942818
31 + 942787 = 942818
109 + 942709 = 942818
127 + 942691 = 942818
157 + 942661 = 942818
181 + 942637 = 942818
211 + 942607 = 942818
241 + 942577 = 942818

Showing the first eight; more decompositions exist.
