Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87250, here are decompositions:

29 + 87221 = 87250
71 + 87179 = 87250
101 + 87149 = 87250
131 + 87119 = 87250
167 + 87083 = 87250
179 + 87071 = 87250
239 + 87011 = 87250
257 + 86993 = 87250

Showing the first eight; more decompositions exist.
