Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87300, here are decompositions:

7 + 87293 = 87300
19 + 87281 = 87300
23 + 87277 = 87300
43 + 87257 = 87300
47 + 87253 = 87300
79 + 87221 = 87300
89 + 87211 = 87300
113 + 87187 = 87300

Showing the first eight; more decompositions exist.
