Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720874, here are decompositions:

37 + 8720837 = 8720874
67 + 8720807 = 8720874
101 + 8720773 = 8720874
103 + 8720771 = 8720874
167 + 8720707 = 8720874
181 + 8720693 = 8720874
193 + 8720681 = 8720874
251 + 8720623 = 8720874

Showing the first eight; more decompositions exist.
