Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87448, here are decompositions:

5 + 87443 = 87448
41 + 87407 = 87448
89 + 87359 = 87448
131 + 87317 = 87448
149 + 87299 = 87448
167 + 87281 = 87448
191 + 87257 = 87448
197 + 87251 = 87448

Showing the first eight; more decompositions exist.
