Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623238, here are decompositions:

97 + 8623141 = 8623238
157 + 8623081 = 8623238
199 + 8623039 = 8623238
367 + 8622871 = 8623238
397 + 8622841 = 8623238
457 + 8622781 = 8623238
661 + 8622577 = 8623238
709 + 8622529 = 8623238

Showing the first eight; more decompositions exist.
