Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724452, here are decompositions:

31 + 8724421 = 8724452
151 + 8724301 = 8724452
193 + 8724259 = 8724452
199 + 8724253 = 8724452
211 + 8724241 = 8724452
229 + 8724223 = 8724452
271 + 8724181 = 8724452
283 + 8724169 = 8724452

Showing the first eight; more decompositions exist.
