Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646990, here are decompositions:

19 + 8646971 = 8646990
29 + 8646961 = 8646990
41 + 8646949 = 8646990
43 + 8646947 = 8646990
47 + 8646943 = 8646990
61 + 8646929 = 8646990
101 + 8646889 = 8646990
137 + 8646853 = 8646990

Showing the first eight; more decompositions exist.
