Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722002, here are decompositions:

5 + 8721997 = 8722002
13 + 8721989 = 8722002
61 + 8721941 = 8722002
73 + 8721929 = 8722002
89 + 8721913 = 8722002
151 + 8721851 = 8722002
229 + 8721773 = 8722002
239 + 8721763 = 8722002

Showing the first eight; more decompositions exist.
