Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662872, here are decompositions:

5 + 8662867 = 8662872
13 + 8662859 = 8662872
19 + 8662853 = 8662872
41 + 8662831 = 8662872
61 + 8662811 = 8662872
73 + 8662799 = 8662872
89 + 8662783 = 8662872
103 + 8662769 = 8662872

Showing the first eight; more decompositions exist.
