Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752642, here are decompositions:

23 + 8752619 = 8752642
29 + 8752613 = 8752642
89 + 8752553 = 8752642
131 + 8752511 = 8752642
263 + 8752379 = 8752642
281 + 8752361 = 8752642
389 + 8752253 = 8752642
461 + 8752181 = 8752642

Showing the first eight; more decompositions exist.
