Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648872, here are decompositions:

5 + 8648867 = 8648872
41 + 8648831 = 8648872
59 + 8648813 = 8648872
131 + 8648741 = 8648872
359 + 8648513 = 8648872
503 + 8648369 = 8648872
761 + 8648111 = 8648872
773 + 8648099 = 8648872

Showing the first eight; more decompositions exist.
