Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752540, here are decompositions:

3 + 8752537 = 8752540
29 + 8752511 = 8752540
113 + 8752427 = 8752540
179 + 8752361 = 8752540
353 + 8752187 = 8752540
359 + 8752181 = 8752540
383 + 8752157 = 8752540
509 + 8752031 = 8752540

Showing the first eight; more decompositions exist.
