Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87902, here are decompositions:

109 + 87793 = 87902
151 + 87751 = 87902
163 + 87739 = 87902
181 + 87721 = 87902
211 + 87691 = 87902
223 + 87679 = 87902
271 + 87631 = 87902
313 + 87589 = 87902

Showing the first eight; more decompositions exist.
