Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722972, here are decompositions:

3 + 8722969 = 8722972
23 + 8722949 = 8722972
59 + 8722913 = 8722972
113 + 8722859 = 8722972
131 + 8722841 = 8722972
173 + 8722799 = 8722972
233 + 8722739 = 8722972
311 + 8722661 = 8722972

Showing the first eight; more decompositions exist.
