Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725226, here are decompositions:

7 + 8725219 = 8725226
19 + 8725207 = 8725226
43 + 8725183 = 8725226
67 + 8725159 = 8725226
73 + 8725153 = 8725226
79 + 8725147 = 8725226
127 + 8725099 = 8725226
277 + 8724949 = 8725226

Showing the first eight; more decompositions exist.
