Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621992, here are decompositions:

3 + 8621989 = 8621992
53 + 8621939 = 8621992
59 + 8621933 = 8621992
131 + 8621861 = 8621992
149 + 8621843 = 8621992
173 + 8621819 = 8621992
311 + 8621681 = 8621992
383 + 8621609 = 8621992

Showing the first eight; more decompositions exist.
