Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691308, here are decompositions:

61 + 8691247 = 8691308
79 + 8691229 = 8691308
97 + 8691211 = 8691308
151 + 8691157 = 8691308
181 + 8691127 = 8691308
337 + 8690971 = 8691308
349 + 8690959 = 8691308
487 + 8690821 = 8691308

Showing the first eight; more decompositions exist.
