Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623198, here are decompositions:

5 + 8623193 = 8623198
131 + 8623067 = 8623198
137 + 8623061 = 8623198
167 + 8623031 = 8623198
179 + 8623019 = 8623198
239 + 8622959 = 8623198
431 + 8622767 = 8623198
491 + 8622707 = 8623198

Showing the first eight; more decompositions exist.
