Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622992, here are decompositions:

19 + 8622973 = 8622992
109 + 8622883 = 8622992
139 + 8622853 = 8622992
151 + 8622841 = 8622992
181 + 8622811 = 8622992
199 + 8622793 = 8622992
211 + 8622781 = 8622992
229 + 8622763 = 8622992

Showing the first eight; more decompositions exist.
