Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731698, here are decompositions:

11 + 8731687 = 8731698
37 + 8731661 = 8731698
61 + 8731637 = 8731698
71 + 8731627 = 8731698
89 + 8731609 = 8731698
127 + 8731571 = 8731698
167 + 8731531 = 8731698
197 + 8731501 = 8731698

Showing the first eight; more decompositions exist.
