Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87330, here are decompositions:

7 + 87323 = 87330
13 + 87317 = 87330
17 + 87313 = 87330
31 + 87299 = 87330
37 + 87293 = 87330
53 + 87277 = 87330
73 + 87257 = 87330
79 + 87251 = 87330

Showing the first eight; more decompositions exist.
