Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601998, here are decompositions:

7 + 8601991 = 8601998
19 + 8601979 = 8601998
37 + 8601961 = 8601998
61 + 8601937 = 8601998
271 + 8601727 = 8601998
331 + 8601667 = 8601998
367 + 8601631 = 8601998
487 + 8601511 = 8601998

Showing the first eight; more decompositions exist.
