Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723272, here are decompositions:

29 + 8723243 = 8723272
59 + 8723213 = 8723272
149 + 8723123 = 8723272
191 + 8723081 = 8723272
281 + 8722991 = 8723272
359 + 8722913 = 8723272
431 + 8722841 = 8723272
443 + 8722829 = 8723272

Showing the first eight; more decompositions exist.
