Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725242, here are decompositions:

23 + 8725219 = 8725242
59 + 8725183 = 8725242
83 + 8725159 = 8725242
89 + 8725153 = 8725242
101 + 8725141 = 8725242
103 + 8725139 = 8725242
109 + 8725133 = 8725242
131 + 8725111 = 8725242

Showing the first eight; more decompositions exist.
