Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725938, here are decompositions:

7 + 8725931 = 8725938
61 + 8725877 = 8725938
97 + 8725841 = 8725938
107 + 8725831 = 8725938
139 + 8725799 = 8725938
181 + 8725757 = 8725938
239 + 8725699 = 8725938
257 + 8725681 = 8725938

Showing the first eight; more decompositions exist.
