Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702, here are decompositions:

3 + 8699 = 8702
13 + 8689 = 8702
61 + 8641 = 8702
73 + 8629 = 8702
79 + 8623 = 8702
103 + 8599 = 8702
139 + 8563 = 8702
163 + 8539 = 8702

Showing the first eight; more decompositions exist.
