Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723412, here are decompositions:

13 + 8723399 = 8723412
53 + 8723359 = 8723412
59 + 8723353 = 8723412
101 + 8723311 = 8723412
109 + 8723303 = 8723412
199 + 8723213 = 8723412
263 + 8723149 = 8723412
331 + 8723081 = 8723412

Showing the first eight; more decompositions exist.
