Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723928, here are decompositions:

7 + 8723921 = 8723928
19 + 8723909 = 8723928
29 + 8723899 = 8723928
41 + 8723887 = 8723928
107 + 8723821 = 8723928
139 + 8723789 = 8723928
197 + 8723731 = 8723928
251 + 8723677 = 8723928

Showing the first eight; more decompositions exist.
