Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720852, here are decompositions:

13 + 8720839 = 8720852
43 + 8720809 = 8720852
79 + 8720773 = 8720852
139 + 8720713 = 8720852
163 + 8720689 = 8720852
181 + 8720671 = 8720852
223 + 8720629 = 8720852
229 + 8720623 = 8720852

Showing the first eight; more decompositions exist.
