Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712184, here are decompositions:

3 + 8712181 = 8712184
11 + 8712173 = 8712184
17 + 8712167 = 8712184
71 + 8712113 = 8712184
167 + 8712017 = 8712184
197 + 8711987 = 8712184
233 + 8711951 = 8712184
251 + 8711933 = 8712184

Showing the first eight; more decompositions exist.
