Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691994, here are decompositions:

23 + 8691971 = 8691994
53 + 8691941 = 8691994
71 + 8691923 = 8691994
167 + 8691827 = 8691994
191 + 8691803 = 8691994
263 + 8691731 = 8691994
401 + 8691593 = 8691994
587 + 8691407 = 8691994

Showing the first eight; more decompositions exist.
