Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691382, here are decompositions:

23 + 8691359 = 8691382
83 + 8691299 = 8691382
101 + 8691281 = 8691382
113 + 8691269 = 8691382
131 + 8691251 = 8691382
173 + 8691209 = 8691382
263 + 8691119 = 8691382
281 + 8691101 = 8691382

Showing the first eight; more decompositions exist.
