Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87340, here are decompositions:

3 + 87337 = 87340
17 + 87323 = 87340
23 + 87317 = 87340
41 + 87299 = 87340
47 + 87293 = 87340
59 + 87281 = 87340
83 + 87257 = 87340
89 + 87251 = 87340

Showing the first eight; more decompositions exist.
