Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691368, here are decompositions:

139 + 8691229 = 8691368
157 + 8691211 = 8691368
181 + 8691187 = 8691368
211 + 8691157 = 8691368
241 + 8691127 = 8691368
277 + 8691091 = 8691368
349 + 8691019 = 8691368
397 + 8690971 = 8691368

Showing the first eight; more decompositions exist.
