Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87406, here are decompositions:

3 + 87403 = 87406
23 + 87383 = 87406
47 + 87359 = 87406
83 + 87323 = 87406
89 + 87317 = 87406
107 + 87299 = 87406
113 + 87293 = 87406
149 + 87257 = 87406

Showing the first eight; more decompositions exist.
