Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678172, here are decompositions:

11 + 8678161 = 8678172
23 + 8678149 = 8678172
31 + 8678141 = 8678172
43 + 8678129 = 8678172
59 + 8678113 = 8678172
79 + 8678093 = 8678172
89 + 8678083 = 8678172
103 + 8678069 = 8678172

Showing the first eight; more decompositions exist.
