Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87338, here are decompositions:

61 + 87277 = 87338
127 + 87211 = 87338
151 + 87187 = 87338
157 + 87181 = 87338
379 + 86959 = 87338
409 + 86929 = 87338
487 + 86851 = 87338
571 + 86767 = 87338

Showing the first eight; more decompositions exist.
