Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731726, here are decompositions:

5 + 8731721 = 8731726
53 + 8731673 = 8731726
83 + 8731643 = 8731726
89 + 8731637 = 8731726
197 + 8731529 = 8731726
233 + 8731493 = 8731726
293 + 8731433 = 8731726
383 + 8731343 = 8731726

Showing the first eight; more decompositions exist.
