Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646400, here are decompositions:

11 + 8646389 = 8646400
23 + 8646377 = 8646400
71 + 8646329 = 8646400
83 + 8646317 = 8646400
101 + 8646299 = 8646400
107 + 8646293 = 8646400
131 + 8646269 = 8646400
167 + 8646233 = 8646400

Showing the first eight; more decompositions exist.
