Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604072, here are decompositions:

5 + 8604067 = 8604072
13 + 8604059 = 8604072
109 + 8603963 = 8604072
179 + 8603893 = 8604072
229 + 8603843 = 8604072
233 + 8603839 = 8604072
241 + 8603831 = 8604072
293 + 8603779 = 8604072

Showing the first eight; more decompositions exist.
