Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697040, here are decompositions:

3 + 8697037 = 8697040
41 + 8696999 = 8697040
47 + 8696993 = 8697040
89 + 8696951 = 8697040
101 + 8696939 = 8697040
137 + 8696903 = 8697040
173 + 8696867 = 8697040
251 + 8696789 = 8697040

Showing the first eight; more decompositions exist.
