Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731474, here are decompositions:

41 + 8731433 = 8731474
47 + 8731427 = 8731474
131 + 8731343 = 8731474
173 + 8731301 = 8731474
197 + 8731277 = 8731474
263 + 8731211 = 8731474
443 + 8731031 = 8731474
491 + 8730983 = 8731474

Showing the first eight; more decompositions exist.
