Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748512, here are decompositions:

13 + 8748499 = 8748512
43 + 8748469 = 8748512
109 + 8748403 = 8748512
151 + 8748361 = 8748512
181 + 8748331 = 8748512
313 + 8748199 = 8748512
541 + 8747971 = 8748512
571 + 8747941 = 8748512

Showing the first eight; more decompositions exist.
