Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981822, here are decompositions:

5 + 981817 = 981822
11 + 981811 = 981822
13 + 981809 = 981822
53 + 981769 = 981822
109 + 981713 = 981822
131 + 981691 = 981822
139 + 981683 = 981822
199 + 981623 = 981822

Showing the first eight; more decompositions exist.
