Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87184, here are decompositions:

3 + 87181 = 87184
5 + 87179 = 87184
101 + 87083 = 87184
113 + 87071 = 87184
173 + 87011 = 87184
191 + 86993 = 87184
233 + 86951 = 87184
257 + 86927 = 87184

Showing the first eight; more decompositions exist.
