Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624028, here are decompositions:

5 + 8624023 = 8624028
11 + 8624017 = 8624028
19 + 8624009 = 8624028
59 + 8623969 = 8624028
67 + 8623961 = 8624028
89 + 8623939 = 8624028
131 + 8623897 = 8624028
181 + 8623847 = 8624028

Showing the first eight; more decompositions exist.
