Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731516, here are decompositions:

5 + 8731511 = 8731516
23 + 8731493 = 8731516
83 + 8731433 = 8731516
89 + 8731427 = 8731516
173 + 8731343 = 8731516
239 + 8731277 = 8731516
419 + 8731097 = 8731516
569 + 8730947 = 8731516

Showing the first eight; more decompositions exist.
