Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621954, here are decompositions:

7 + 8621947 = 8621954
43 + 8621911 = 8621954
97 + 8621857 = 8621954
127 + 8621827 = 8621954
157 + 8621797 = 8621954
181 + 8621773 = 8621954
277 + 8621677 = 8621954
331 + 8621623 = 8621954

Showing the first eight; more decompositions exist.
