Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724726, here are decompositions:

5 + 8724721 = 8724726
7 + 8724719 = 8724726
13 + 8724713 = 8724726
29 + 8724697 = 8724726
83 + 8724643 = 8724726
107 + 8724619 = 8724726
137 + 8724589 = 8724726
167 + 8724559 = 8724726

Showing the first eight; more decompositions exist.
