Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622012, here are decompositions:

5 + 8622007 = 8622012
11 + 8622001 = 8622012
23 + 8621989 = 8622012
29 + 8621983 = 8622012
41 + 8621971 = 8622012
53 + 8621959 = 8622012
73 + 8621939 = 8622012
79 + 8621933 = 8622012

Showing the first eight; more decompositions exist.
