Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702140, here are decompositions:

3 + 8702137 = 8702140
47 + 8702093 = 8702140
89 + 8702051 = 8702140
131 + 8702009 = 8702140
149 + 8701991 = 8702140
179 + 8701961 = 8702140
191 + 8701949 = 8702140
233 + 8701907 = 8702140

Showing the first eight; more decompositions exist.
