Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618382, here are decompositions:

5 + 8618377 = 8618382
43 + 8618339 = 8618382
53 + 8618329 = 8618382
89 + 8618293 = 8618382
109 + 8618273 = 8618382
131 + 8618251 = 8618382
139 + 8618243 = 8618382
233 + 8618149 = 8618382

Showing the first eight; more decompositions exist.
