Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732220, here are decompositions:

11 + 8732209 = 8732220
19 + 8732201 = 8732220
23 + 8732197 = 8732220
31 + 8732189 = 8732220
61 + 8732159 = 8732220
83 + 8732137 = 8732220
97 + 8732123 = 8732220
103 + 8732117 = 8732220

Showing the first eight; more decompositions exist.
