Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723344, here are decompositions:

23 + 8723321 = 8723344
41 + 8723303 = 8723344
101 + 8723243 = 8723344
131 + 8723213 = 8723344
263 + 8723081 = 8723344
281 + 8723063 = 8723344
353 + 8722991 = 8723344
431 + 8722913 = 8723344

Showing the first eight; more decompositions exist.
