Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752840, here are decompositions:

17 + 8752823 = 8752840
23 + 8752817 = 8752840
59 + 8752781 = 8752840
71 + 8752769 = 8752840
197 + 8752643 = 8752840
227 + 8752613 = 8752840
419 + 8752421 = 8752840
461 + 8752379 = 8752840

Showing the first eight; more decompositions exist.
