Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731692, here are decompositions:

5 + 8731687 = 8731692
19 + 8731673 = 8731692
31 + 8731661 = 8731692
83 + 8731609 = 8731692
113 + 8731579 = 8731692
163 + 8731529 = 8731692
181 + 8731511 = 8731692
191 + 8731501 = 8731692

Showing the first eight; more decompositions exist.
