Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702156, here are decompositions:

7 + 8702149 = 8702156
19 + 8702137 = 8702156
157 + 8701999 = 8702156
223 + 8701933 = 8702156
283 + 8701873 = 8702156
367 + 8701789 = 8702156
409 + 8701747 = 8702156
433 + 8701723 = 8702156

Showing the first eight; more decompositions exist.
