Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646738, here are decompositions:

17 + 8646721 = 8646738
19 + 8646719 = 8646738
29 + 8646709 = 8646738
31 + 8646707 = 8646738
71 + 8646667 = 8646738
131 + 8646607 = 8646738
157 + 8646581 = 8646738
167 + 8646571 = 8646738

Showing the first eight; more decompositions exist.
