Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87248, here are decompositions:

37 + 87211 = 87248
61 + 87187 = 87248
67 + 87181 = 87248
97 + 87151 = 87248
127 + 87121 = 87248
199 + 87049 = 87248
211 + 87037 = 87248
379 + 86869 = 87248

Showing the first eight; more decompositions exist.
