Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712126, here are decompositions:

13 + 8712113 = 8712126
67 + 8712059 = 8712126
97 + 8712029 = 8712126
107 + 8712019 = 8712126
109 + 8712017 = 8712126
139 + 8711987 = 8712126
173 + 8711953 = 8712126
193 + 8711933 = 8712126

Showing the first eight; more decompositions exist.
