Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87348, here are decompositions:

11 + 87337 = 87348
31 + 87317 = 87348
67 + 87281 = 87348
71 + 87277 = 87348
97 + 87251 = 87348
127 + 87221 = 87348
137 + 87211 = 87348
167 + 87181 = 87348

Showing the first eight; more decompositions exist.
