Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722140, here are decompositions:

17 + 8722123 = 8722140
23 + 8722117 = 8722140
41 + 8722099 = 8722140
43 + 8722097 = 8722140
47 + 8722093 = 8722140
59 + 8722081 = 8722140
61 + 8722079 = 8722140
107 + 8722033 = 8722140

Showing the first eight; more decompositions exist.
