Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619822, here are decompositions:

5 + 8619817 = 8619822
11 + 8619811 = 8619822
31 + 8619791 = 8619822
103 + 8619719 = 8619822
109 + 8619713 = 8619822
139 + 8619683 = 8619822
173 + 8619649 = 8619822
199 + 8619623 = 8619822

Showing the first eight; more decompositions exist.
