Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732440, here are decompositions:

11 + 8732429 = 8732440
23 + 8732417 = 8732440
29 + 8732411 = 8732440
71 + 8732369 = 8732440
89 + 8732351 = 8732440
131 + 8732309 = 8732440
149 + 8732291 = 8732440
179 + 8732261 = 8732440

Showing the first eight; more decompositions exist.
