Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623424, here are decompositions:

31 + 8623393 = 8623424
67 + 8623357 = 8623424
163 + 8623261 = 8623424
211 + 8623213 = 8623424
283 + 8623141 = 8623424
373 + 8623051 = 8623424
421 + 8623003 = 8623424
541 + 8622883 = 8623424

Showing the first eight; more decompositions exist.
