Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694228, here are decompositions:

7 + 8694221 = 8694228
17 + 8694211 = 8694228
31 + 8694197 = 8694228
97 + 8694131 = 8694228
131 + 8694097 = 8694228
149 + 8694079 = 8694228
181 + 8694047 = 8694228
197 + 8694031 = 8694228

Showing the first eight; more decompositions exist.
