Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712210, here are decompositions:

29 + 8712181 = 8712210
37 + 8712173 = 8712210
41 + 8712169 = 8712210
43 + 8712167 = 8712210
47 + 8712163 = 8712210
53 + 8712157 = 8712210
61 + 8712149 = 8712210
97 + 8712113 = 8712210

Showing the first eight; more decompositions exist.
