Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615946, here are decompositions:

5 + 8615941 = 8615946
29 + 8615917 = 8615946
67 + 8615879 = 8615946
113 + 8615833 = 8615946
137 + 8615809 = 8615946
179 + 8615767 = 8615946
197 + 8615749 = 8615946
223 + 8615723 = 8615946

Showing the first eight; more decompositions exist.
