Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634320, here are decompositions:

61 + 8634259 = 8634320
67 + 8634253 = 8634320
109 + 8634211 = 8634320
151 + 8634169 = 8634320
157 + 8634163 = 8634320
181 + 8634139 = 8634320
271 + 8634049 = 8634320
337 + 8633983 = 8634320

Showing the first eight; more decompositions exist.
