Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691342, here are decompositions:

29 + 8691313 = 8691342
43 + 8691299 = 8691342
61 + 8691281 = 8691342
73 + 8691269 = 8691342
103 + 8691239 = 8691342
113 + 8691229 = 8691342
131 + 8691211 = 8691342
223 + 8691119 = 8691342

Showing the first eight; more decompositions exist.
