Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87364, here are decompositions:

5 + 87359 = 87364
41 + 87323 = 87364
47 + 87317 = 87364
71 + 87293 = 87364
83 + 87281 = 87364
107 + 87257 = 87364
113 + 87251 = 87364
257 + 87107 = 87364

Showing the first eight; more decompositions exist.
