Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623156, here are decompositions:

53 + 8623103 = 8623156
83 + 8623073 = 8623156
89 + 8623067 = 8623156
137 + 8623019 = 8623156
173 + 8622983 = 8623156
197 + 8622959 = 8623156
233 + 8622923 = 8623156
389 + 8622767 = 8623156

Showing the first eight; more decompositions exist.
