Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707170, here are decompositions:

11 + 8707159 = 8707170
23 + 8707147 = 8707170
47 + 8707123 = 8707170
67 + 8707103 = 8707170
79 + 8707091 = 8707170
113 + 8707057 = 8707170
139 + 8707031 = 8707170
149 + 8707021 = 8707170

Showing the first eight; more decompositions exist.
