Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634840, here are decompositions:

17 + 8634823 = 8634840
29 + 8634811 = 8634840
37 + 8634803 = 8634840
73 + 8634767 = 8634840
79 + 8634761 = 8634840
89 + 8634751 = 8634840
127 + 8634713 = 8634840
163 + 8634677 = 8634840

Showing the first eight; more decompositions exist.
