Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634156, here are decompositions:

17 + 8634139 = 8634156
19 + 8634137 = 8634156
23 + 8634133 = 8634156
79 + 8634077 = 8634156
103 + 8634053 = 8634156
107 + 8634049 = 8634156
173 + 8633983 = 8634156
197 + 8633959 = 8634156

Showing the first eight; more decompositions exist.
