Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657904, here are decompositions:

23 + 8657881 = 8657904
53 + 8657851 = 8657904
71 + 8657833 = 8657904
103 + 8657801 = 8657904
137 + 8657767 = 8657904
173 + 8657731 = 8657904
181 + 8657723 = 8657904
223 + 8657681 = 8657904

Showing the first eight; more decompositions exist.
