Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691116, here are decompositions:

73 + 8691043 = 8691116
97 + 8691019 = 8691116
157 + 8690959 = 8691116
163 + 8690953 = 8691116
199 + 8690917 = 8691116
349 + 8690767 = 8691116
433 + 8690683 = 8691116
439 + 8690677 = 8691116

Showing the first eight; more decompositions exist.
