Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691236, here are decompositions:

7 + 8691229 = 8691236
13 + 8691223 = 8691236
79 + 8691157 = 8691236
109 + 8691127 = 8691236
193 + 8691043 = 8691236
277 + 8690959 = 8691236
283 + 8690953 = 8691236
409 + 8690827 = 8691236

Showing the first eight; more decompositions exist.
