Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623228, here are decompositions:

167 + 8623061 = 8623228
191 + 8623037 = 8623228
197 + 8623031 = 8623228
269 + 8622959 = 8623228
461 + 8622767 = 8623228
521 + 8622707 = 8623228
617 + 8622611 = 8623228
941 + 8622287 = 8623228

Showing the first eight; more decompositions exist.
