Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646370, here are decompositions:

41 + 8646329 = 8646370
53 + 8646317 = 8646370
71 + 8646299 = 8646370
101 + 8646269 = 8646370
113 + 8646257 = 8646370
137 + 8646233 = 8646370
149 + 8646221 = 8646370
251 + 8646119 = 8646370

Showing the first eight; more decompositions exist.
