Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724404, here are decompositions:

103 + 8724301 = 8724404
151 + 8724253 = 8724404
163 + 8724241 = 8724404
181 + 8724223 = 8724404
223 + 8724181 = 8724404
277 + 8724127 = 8724404
331 + 8724073 = 8724404
457 + 8723947 = 8724404

Showing the first eight; more decompositions exist.
