Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680980, here are decompositions:

29 + 8680951 = 8680980
41 + 8680939 = 8680980
59 + 8680921 = 8680980
71 + 8680909 = 8680980
73 + 8680907 = 8680980
79 + 8680901 = 8680980
109 + 8680871 = 8680980
157 + 8680823 = 8680980

Showing the first eight; more decompositions exist.
