Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712172, here are decompositions:

3 + 8712169 = 8712172
5 + 8712167 = 8712172
23 + 8712149 = 8712172
59 + 8712113 = 8712172
113 + 8712059 = 8712172
239 + 8711933 = 8712172
251 + 8711921 = 8712172
389 + 8711783 = 8712172

Showing the first eight; more decompositions exist.
