Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701688, here are decompositions:

31 + 8701657 = 8701688
67 + 8701621 = 8701688
157 + 8701531 = 8701688
181 + 8701507 = 8701688
199 + 8701489 = 8701688
211 + 8701477 = 8701688
241 + 8701447 = 8701688
367 + 8701321 = 8701688

Showing the first eight; more decompositions exist.
