Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623998, here are decompositions:

29 + 8623969 = 8623998
37 + 8623961 = 8623998
59 + 8623939 = 8623998
101 + 8623897 = 8623998
151 + 8623847 = 8623998
167 + 8623831 = 8623998
191 + 8623807 = 8623998
197 + 8623801 = 8623998

Showing the first eight; more decompositions exist.
