Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8872, here are decompositions:

5 + 8867 = 8872
11 + 8861 = 8872
23 + 8849 = 8872
41 + 8831 = 8872
53 + 8819 = 8872
89 + 8783 = 8872
131 + 8741 = 8872
173 + 8699 = 8872

Showing the first eight; more decompositions exist.
