Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601980, here are decompositions:

19 + 8601961 = 8601980
43 + 8601937 = 8601980
73 + 8601907 = 8601980
97 + 8601883 = 8601980
103 + 8601877 = 8601980
157 + 8601823 = 8601980
241 + 8601739 = 8601980
313 + 8601667 = 8601980

Showing the first eight; more decompositions exist.
