Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87484, here are decompositions:

3 + 87481 = 87484
11 + 87473 = 87484
41 + 87443 = 87484
101 + 87383 = 87484
167 + 87317 = 87484
191 + 87293 = 87484
227 + 87257 = 87484
233 + 87251 = 87484

Showing the first eight; more decompositions exist.
