Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87308, here are decompositions:

31 + 87277 = 87308
97 + 87211 = 87308
127 + 87181 = 87308
157 + 87151 = 87308
271 + 87037 = 87308
349 + 86959 = 87308
379 + 86929 = 87308
439 + 86869 = 87308

Showing the first eight; more decompositions exist.
