Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725394, here are decompositions:

3 + 8725391 = 8725394
31 + 8725363 = 8725394
37 + 8725357 = 8725394
151 + 8725243 = 8725394
211 + 8725183 = 8725394
241 + 8725153 = 8725394
283 + 8725111 = 8725394
373 + 8725021 = 8725394

Showing the first eight; more decompositions exist.
