Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691126, here are decompositions:

7 + 8691119 = 8691126
83 + 8691043 = 8691126
107 + 8691019 = 8691126
163 + 8690963 = 8691126
167 + 8690959 = 8691126
173 + 8690953 = 8691126
179 + 8690947 = 8691126
313 + 8690813 = 8691126

Showing the first eight; more decompositions exist.
