Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87538, here are decompositions:

29 + 87509 = 87538
47 + 87491 = 87538
131 + 87407 = 87538
179 + 87359 = 87538
239 + 87299 = 87538
257 + 87281 = 87538
281 + 87257 = 87538
317 + 87221 = 87538

Showing the first eight; more decompositions exist.
