Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667972, here are decompositions:

11 + 8667961 = 8667972
23 + 8667949 = 8667972
41 + 8667931 = 8667972
43 + 8667929 = 8667972
59 + 8667913 = 8667972
73 + 8667899 = 8667972
101 + 8667871 = 8667972
109 + 8667863 = 8667972

Showing the first eight; more decompositions exist.
