Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731672, here are decompositions:

11 + 8731661 = 8731672
29 + 8731643 = 8731672
101 + 8731571 = 8731672
179 + 8731493 = 8731672
239 + 8731433 = 8731672
359 + 8731313 = 8731672
461 + 8731211 = 8731672
563 + 8731109 = 8731672

Showing the first eight; more decompositions exist.
