Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702158, here are decompositions:

107 + 8702051 = 8702158
149 + 8702009 = 8702158
167 + 8701991 = 8702158
197 + 8701961 = 8702158
251 + 8701907 = 8702158
281 + 8701877 = 8702158
347 + 8701811 = 8702158
401 + 8701757 = 8702158

Showing the first eight; more decompositions exist.
