Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724192, here are decompositions:

11 + 8724181 = 8724192
23 + 8724169 = 8724192
31 + 8724161 = 8724192
53 + 8724139 = 8724192
179 + 8724013 = 8724192
199 + 8723993 = 8724192
241 + 8723951 = 8724192
263 + 8723929 = 8724192

Showing the first eight; more decompositions exist.
