Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728396, here are decompositions:

23 + 8728373 = 8728396
107 + 8728289 = 8728396
227 + 8728169 = 8728396
317 + 8728079 = 8728396
359 + 8728037 = 8728396
587 + 8727809 = 8728396
617 + 8727779 = 8728396
773 + 8727623 = 8728396

Showing the first eight; more decompositions exist.
