Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691084, here are decompositions:

41 + 8691043 = 8691084
113 + 8690971 = 8691084
131 + 8690953 = 8691084
137 + 8690947 = 8691084
163 + 8690921 = 8691084
167 + 8690917 = 8691084
257 + 8690827 = 8691084
263 + 8690821 = 8691084

Showing the first eight; more decompositions exist.
