Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731792, here are decompositions:

5 + 8731787 = 8731792
29 + 8731763 = 8731792
71 + 8731721 = 8731792
131 + 8731661 = 8731792
149 + 8731643 = 8731792
263 + 8731529 = 8731792
281 + 8731511 = 8731792
359 + 8731433 = 8731792

Showing the first eight; more decompositions exist.
