Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702130, here are decompositions:

23 + 8702107 = 8702130
37 + 8702093 = 8702130
67 + 8702063 = 8702130
79 + 8702051 = 8702130
131 + 8701999 = 8702130
139 + 8701991 = 8702130
179 + 8701951 = 8702130
181 + 8701949 = 8702130

Showing the first eight; more decompositions exist.
