Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621906, here are decompositions:

37 + 8621869 = 8621906
43 + 8621863 = 8621906
79 + 8621827 = 8621906
109 + 8621797 = 8621906
127 + 8621779 = 8621906
157 + 8621749 = 8621906
199 + 8621707 = 8621906
229 + 8621677 = 8621906

Showing the first eight; more decompositions exist.
