Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723448, here are decompositions:

7 + 8723441 = 8723448
11 + 8723437 = 8723448
29 + 8723419 = 8723448
61 + 8723387 = 8723448
89 + 8723359 = 8723448
101 + 8723347 = 8723448
127 + 8723321 = 8723448
131 + 8723317 = 8723448

Showing the first eight; more decompositions exist.
