Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87454, here are decompositions:

11 + 87443 = 87454
47 + 87407 = 87454
71 + 87383 = 87454
131 + 87323 = 87454
137 + 87317 = 87454
173 + 87281 = 87454
197 + 87257 = 87454
233 + 87221 = 87454

Showing the first eight; more decompositions exist.
