Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668260, here are decompositions:

53 + 8668207 = 8668260
59 + 8668201 = 8668260
67 + 8668193 = 8668260
103 + 8668157 = 8668260
109 + 8668151 = 8668260
127 + 8668133 = 8668260
149 + 8668111 = 8668260
179 + 8668081 = 8668260

Showing the first eight; more decompositions exist.
