Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691188, here are decompositions:

31 + 8691157 = 8691188
61 + 8691127 = 8691188
97 + 8691091 = 8691188
229 + 8690959 = 8691188
241 + 8690947 = 8691188
271 + 8690917 = 8691188
367 + 8690821 = 8691188
421 + 8690767 = 8691188

Showing the first eight; more decompositions exist.
