Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697874, here are decompositions:

5 + 8697869 = 8697874
23 + 8697851 = 8697874
41 + 8697833 = 8697874
71 + 8697803 = 8697874
83 + 8697791 = 8697874
167 + 8697707 = 8697874
191 + 8697683 = 8697874
197 + 8697677 = 8697874

Showing the first eight; more decompositions exist.
