Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731666, here are decompositions:

5 + 8731661 = 8731666
23 + 8731643 = 8731666
29 + 8731637 = 8731666
59 + 8731607 = 8731666
137 + 8731529 = 8731666
173 + 8731493 = 8731666
233 + 8731433 = 8731666
239 + 8731427 = 8731666

Showing the first eight; more decompositions exist.
