Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724422, here are decompositions:

103 + 8724319 = 8724422
139 + 8724283 = 8724422
163 + 8724259 = 8724422
181 + 8724241 = 8724422
199 + 8724223 = 8724422
241 + 8724181 = 8724422
283 + 8724139 = 8724422
349 + 8724073 = 8724422

Showing the first eight; more decompositions exist.
