Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731798, here are decompositions:

11 + 8731787 = 8731798
41 + 8731757 = 8731798
137 + 8731661 = 8731798
191 + 8731607 = 8731798
227 + 8731571 = 8731798
269 + 8731529 = 8731798
521 + 8731277 = 8731798
587 + 8731211 = 8731798

Showing the first eight; more decompositions exist.
