Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725206, here are decompositions:

23 + 8725183 = 8725206
29 + 8725177 = 8725206
47 + 8725159 = 8725206
53 + 8725153 = 8725206
59 + 8725147 = 8725206
67 + 8725139 = 8725206
73 + 8725133 = 8725206
103 + 8725103 = 8725206

Showing the first eight; more decompositions exist.
