Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87244, here are decompositions:

23 + 87221 = 87244
137 + 87107 = 87244
173 + 87071 = 87244
233 + 87011 = 87244
251 + 86993 = 87244
263 + 86981 = 87244
293 + 86951 = 87244
317 + 86927 = 87244

Showing the first eight; more decompositions exist.
