Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613972, here are decompositions:

5 + 8613967 = 8613972
11 + 8613961 = 8613972
13 + 8613959 = 8613972
19 + 8613953 = 8613972
43 + 8613929 = 8613972
61 + 8613911 = 8613972
79 + 8613893 = 8613972
109 + 8613863 = 8613972

Showing the first eight; more decompositions exist.
