Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623920, here are decompositions:

17 + 8623903 = 8623920
23 + 8623897 = 8623920
37 + 8623883 = 8623920
73 + 8623847 = 8623920
89 + 8623831 = 8623920
113 + 8623807 = 8623920
127 + 8623793 = 8623920
157 + 8623763 = 8623920

Showing the first eight; more decompositions exist.
