Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691282, here are decompositions:

13 + 8691269 = 8691282
31 + 8691251 = 8691282
43 + 8691239 = 8691282
53 + 8691229 = 8691282
59 + 8691223 = 8691282
71 + 8691211 = 8691282
73 + 8691209 = 8691282
163 + 8691119 = 8691282

Showing the first eight; more decompositions exist.
