Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657040, here are decompositions:

19 + 8657021 = 8657040
23 + 8657017 = 8657040
31 + 8657009 = 8657040
61 + 8656979 = 8657040
101 + 8656939 = 8657040
107 + 8656933 = 8657040
137 + 8656903 = 8657040
149 + 8656891 = 8657040

Showing the first eight; more decompositions exist.
