Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751980, here are decompositions:

7 + 8751973 = 8751980
31 + 8751949 = 8751980
73 + 8751907 = 8751980
109 + 8751871 = 8751980
151 + 8751829 = 8751980
163 + 8751817 = 8751980
199 + 8751781 = 8751980
241 + 8751739 = 8751980

Showing the first eight; more decompositions exist.
