Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637072, here are decompositions:

5 + 8637067 = 8637072
11 + 8637061 = 8637072
13 + 8637059 = 8637072
19 + 8637053 = 8637072
83 + 8636989 = 8637072
113 + 8636959 = 8637072
149 + 8636923 = 8637072
151 + 8636921 = 8637072

Showing the first eight; more decompositions exist.
