Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725222, here are decompositions:

3 + 8725219 = 8725222
5 + 8725217 = 8725222
83 + 8725139 = 8725222
89 + 8725133 = 8725222
131 + 8725091 = 8725222
239 + 8724983 = 8725222
293 + 8724929 = 8725222
419 + 8724803 = 8725222

Showing the first eight; more decompositions exist.
