Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87698, here are decompositions:

7 + 87691 = 87698
19 + 87679 = 87698
67 + 87631 = 87698
109 + 87589 = 87698
139 + 87559 = 87698
151 + 87547 = 87698
157 + 87541 = 87698
181 + 87517 = 87698

Showing the first eight; more decompositions exist.
