Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732398, here are decompositions:

29 + 8732369 = 8732398
47 + 8732351 = 8732398
89 + 8732309 = 8732398
107 + 8732291 = 8732398
137 + 8732261 = 8732398
197 + 8732201 = 8732398
239 + 8732159 = 8732398
281 + 8732117 = 8732398

Showing the first eight; more decompositions exist.
