Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671752, here are decompositions:

13 + 8671739 = 8671752
31 + 8671721 = 8671752
41 + 8671711 = 8671752
43 + 8671709 = 8671752
83 + 8671669 = 8671752
113 + 8671639 = 8671752
163 + 8671589 = 8671752
179 + 8671573 = 8671752

Showing the first eight; more decompositions exist.
