Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712120, here are decompositions:

7 + 8712113 = 8712120
29 + 8712091 = 8712120
61 + 8712059 = 8712120
101 + 8712019 = 8712120
103 + 8712017 = 8712120
149 + 8711971 = 8712120
167 + 8711953 = 8712120
199 + 8711921 = 8712120

Showing the first eight; more decompositions exist.
