Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725940, here are decompositions:

109 + 8725831 = 8725940
127 + 8725813 = 8725940
241 + 8725699 = 8725940
271 + 8725669 = 8725940
283 + 8725657 = 8725940
313 + 8725627 = 8725940
331 + 8725609 = 8725940
373 + 8725567 = 8725940

Showing the first eight; more decompositions exist.
