Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712266, here are decompositions:

7 + 8712259 = 8712266
37 + 8712229 = 8712266
97 + 8712169 = 8712266
103 + 8712163 = 8712266
109 + 8712157 = 8712266
313 + 8711953 = 8712266
379 + 8711887 = 8712266
397 + 8711869 = 8712266

Showing the first eight; more decompositions exist.
