Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731768, here are decompositions:

5 + 8731763 = 8731768
11 + 8731757 = 8731768
47 + 8731721 = 8731768
107 + 8731661 = 8731768
131 + 8731637 = 8731768
197 + 8731571 = 8731768
239 + 8731529 = 8731768
257 + 8731511 = 8731768

Showing the first eight; more decompositions exist.
