Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731684, here are decompositions:

11 + 8731673 = 8731684
23 + 8731661 = 8731684
41 + 8731643 = 8731684
47 + 8731637 = 8731684
113 + 8731571 = 8731684
173 + 8731511 = 8731684
191 + 8731493 = 8731684
251 + 8731433 = 8731684

Showing the first eight; more decompositions exist.
