Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623992, here are decompositions:

23 + 8623969 = 8623992
29 + 8623963 = 8623992
31 + 8623961 = 8623992
53 + 8623939 = 8623992
89 + 8623903 = 8623992
109 + 8623883 = 8623992
149 + 8623843 = 8623992
191 + 8623801 = 8623992

Showing the first eight; more decompositions exist.
