Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725140, here are decompositions:

7 + 8725133 = 8725140
29 + 8725111 = 8725140
37 + 8725103 = 8725140
41 + 8725099 = 8725140
89 + 8725051 = 8725140
101 + 8725039 = 8725140
103 + 8725037 = 8725140
157 + 8724983 = 8725140

Showing the first eight; more decompositions exist.
