Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691924, here are decompositions:

23 + 8691901 = 8691924
41 + 8691883 = 8691924
71 + 8691853 = 8691924
97 + 8691827 = 8691924
173 + 8691751 = 8691924
191 + 8691733 = 8691924
193 + 8691731 = 8691924
251 + 8691673 = 8691924

Showing the first eight; more decompositions exist.
