Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691132, here are decompositions:

5 + 8691127 = 8691132
13 + 8691119 = 8691132
31 + 8691101 = 8691132
41 + 8691091 = 8691132
89 + 8691043 = 8691132
113 + 8691019 = 8691132
173 + 8690959 = 8691132
179 + 8690953 = 8691132

Showing the first eight; more decompositions exist.
