Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752440, here are decompositions:

13 + 8752427 = 8752440
19 + 8752421 = 8752440
23 + 8752417 = 8752440
61 + 8752379 = 8752440
79 + 8752361 = 8752440
101 + 8752339 = 8752440
113 + 8752327 = 8752440
131 + 8752309 = 8752440

Showing the first eight; more decompositions exist.
