Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723912, here are decompositions:

3 + 8723909 = 8723912
13 + 8723899 = 8723912
19 + 8723893 = 8723912
61 + 8723851 = 8723912
79 + 8723833 = 8723912
181 + 8723731 = 8723912
433 + 8723479 = 8723912
601 + 8723311 = 8723912

Showing the first eight; more decompositions exist.
