Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723434, here are decompositions:

11 + 8723423 = 8723434
47 + 8723387 = 8723434
113 + 8723321 = 8723434
131 + 8723303 = 8723434
191 + 8723243 = 8723434
311 + 8723123 = 8723434
353 + 8723081 = 8723434
443 + 8722991 = 8723434

Showing the first eight; more decompositions exist.
