Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724266, here are decompositions:

3 + 8724263 = 8724266
7 + 8724259 = 8724266
13 + 8724253 = 8724266
43 + 8724223 = 8724266
97 + 8724169 = 8724266
127 + 8724139 = 8724266
139 + 8724127 = 8724266
193 + 8724073 = 8724266

Showing the first eight; more decompositions exist.
