Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618256, here are decompositions:

5 + 8618251 = 8618256
13 + 8618243 = 8618256
19 + 8618237 = 8618256
43 + 8618213 = 8618256
83 + 8618173 = 8618256
107 + 8618149 = 8618256
109 + 8618147 = 8618256
137 + 8618119 = 8618256

Showing the first eight; more decompositions exist.
