Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616072, here are decompositions:

29 + 8616043 = 8616072
43 + 8616029 = 8616072
53 + 8616019 = 8616072
61 + 8616011 = 8616072
83 + 8615989 = 8616072
89 + 8615983 = 8616072
109 + 8615963 = 8616072
131 + 8615941 = 8616072

Showing the first eight; more decompositions exist.
