Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732578, here are decompositions:

5 + 8732573 = 8732578
89 + 8732489 = 8732578
131 + 8732447 = 8732578
149 + 8732429 = 8732578
167 + 8732411 = 8732578
227 + 8732351 = 8732578
269 + 8732309 = 8732578
317 + 8732261 = 8732578

Showing the first eight; more decompositions exist.
