Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720974, here are decompositions:

5 + 8720969 = 8720974
83 + 8720891 = 8720974
137 + 8720837 = 8720974
167 + 8720807 = 8720974
191 + 8720783 = 8720974
281 + 8720693 = 8720974
293 + 8720681 = 8720974
347 + 8720627 = 8720974

Showing the first eight; more decompositions exist.
