Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678170, here are decompositions:

23 + 8678147 = 8678170
29 + 8678141 = 8678170
41 + 8678129 = 8678170
89 + 8678081 = 8678170
101 + 8678069 = 8678170
107 + 8678063 = 8678170
113 + 8678057 = 8678170
131 + 8678039 = 8678170

Showing the first eight; more decompositions exist.
