Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646242, here are decompositions:

19 + 8646223 = 8646242
61 + 8646181 = 8646242
79 + 8646163 = 8646242
139 + 8646103 = 8646242
181 + 8646061 = 8646242
271 + 8645971 = 8646242
379 + 8645863 = 8646242
439 + 8645803 = 8646242

Showing the first eight; more decompositions exist.
