Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725180, here are decompositions:

3 + 8725177 = 8725180
41 + 8725139 = 8725180
47 + 8725133 = 8725180
89 + 8725091 = 8725180
197 + 8724983 = 8725180
251 + 8724929 = 8725180
353 + 8724827 = 8725180
461 + 8724719 = 8725180

Showing the first eight; more decompositions exist.
