Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725918, here are decompositions:

41 + 8725877 = 8725918
101 + 8725817 = 8725918
347 + 8725571 = 8725918
419 + 8725499 = 8725918
521 + 8725397 = 8725918
557 + 8725361 = 8725918
599 + 8725319 = 8725918
701 + 8725217 = 8725918

Showing the first eight; more decompositions exist.
