Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732388, here are decompositions:

17 + 8732371 = 8732388
19 + 8732369 = 8732388
37 + 8732351 = 8732388
79 + 8732309 = 8732388
89 + 8732299 = 8732388
97 + 8732291 = 8732388
127 + 8732261 = 8732388
131 + 8732257 = 8732388

Showing the first eight; more decompositions exist.
