Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753220, here are decompositions:

13 + 8753207 = 8753220
17 + 8753203 = 8753220
23 + 8753197 = 8753220
31 + 8753189 = 8753220
43 + 8753177 = 8753220
59 + 8753161 = 8753220
67 + 8753153 = 8753220
71 + 8753149 = 8753220

Showing the first eight; more decompositions exist.
