Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748520, here are decompositions:

17 + 8748503 = 8748520
47 + 8748473 = 8748520
89 + 8748431 = 8748520
101 + 8748419 = 8748520
107 + 8748413 = 8748520
191 + 8748329 = 8748520
197 + 8748323 = 8748520
233 + 8748287 = 8748520

Showing the first eight; more decompositions exist.
