Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87370, here are decompositions:

11 + 87359 = 87370
47 + 87323 = 87370
53 + 87317 = 87370
71 + 87299 = 87370
89 + 87281 = 87370
113 + 87257 = 87370
149 + 87221 = 87370
191 + 87179 = 87370

Showing the first eight; more decompositions exist.
