Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712132, here are decompositions:

19 + 8712113 = 8712132
41 + 8712091 = 8712132
73 + 8712059 = 8712132
103 + 8712029 = 8712132
113 + 8712019 = 8712132
179 + 8711953 = 8712132
181 + 8711951 = 8712132
199 + 8711933 = 8712132

Showing the first eight; more decompositions exist.
