Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748800, here are decompositions:

13 + 8748787 = 8748800
61 + 8748739 = 8748800
127 + 8748673 = 8748800
157 + 8748643 = 8748800
199 + 8748601 = 8748800
211 + 8748589 = 8748800
331 + 8748469 = 8748800
337 + 8748463 = 8748800

Showing the first eight; more decompositions exist.
