Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623208, here are decompositions:

67 + 8623141 = 8623208
127 + 8623081 = 8623208
157 + 8623051 = 8623208
331 + 8622877 = 8623208
337 + 8622871 = 8623208
367 + 8622841 = 8623208
397 + 8622811 = 8623208
487 + 8622721 = 8623208

Showing the first eight; more decompositions exist.
