Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646430, here are decompositions:

29 + 8646401 = 8646430
41 + 8646389 = 8646430
53 + 8646377 = 8646430
101 + 8646329 = 8646430
113 + 8646317 = 8646430
131 + 8646299 = 8646430
137 + 8646293 = 8646430
173 + 8646257 = 8646430

Showing the first eight; more decompositions exist.
