Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712162, here are decompositions:

5 + 8712157 = 8712162
13 + 8712149 = 8712162
29 + 8712133 = 8712162
71 + 8712091 = 8712162
103 + 8712059 = 8712162
191 + 8711971 = 8712162
211 + 8711951 = 8712162
229 + 8711933 = 8712162

Showing the first eight; more decompositions exist.
