Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723406, here are decompositions:

7 + 8723399 = 8723406
19 + 8723387 = 8723406
47 + 8723359 = 8723406
53 + 8723353 = 8723406
59 + 8723347 = 8723406
89 + 8723317 = 8723406
103 + 8723303 = 8723406
163 + 8723243 = 8723406

Showing the first eight; more decompositions exist.
