Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621952, here are decompositions:

5 + 8621947 = 8621952
13 + 8621939 = 8621952
19 + 8621933 = 8621952
41 + 8621911 = 8621952
83 + 8621869 = 8621952
89 + 8621863 = 8621952
109 + 8621843 = 8621952
173 + 8621779 = 8621952

Showing the first eight; more decompositions exist.
