Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758160, here are decompositions:

3 + 8758157 = 8758160
31 + 8758129 = 8758160
43 + 8758117 = 8758160
67 + 8758093 = 8758160
79 + 8758081 = 8758160
157 + 8758003 = 8758160
199 + 8757961 = 8758160
241 + 8757919 = 8758160

Showing the first eight; more decompositions exist.
