Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724426, here are decompositions:

5 + 8724421 = 8724426
79 + 8724347 = 8724426
97 + 8724329 = 8724426
103 + 8724323 = 8724426
107 + 8724319 = 8724426
157 + 8724269 = 8724426
163 + 8724263 = 8724426
167 + 8724259 = 8724426

Showing the first eight; more decompositions exist.
