Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748528, here are decompositions:

29 + 8748499 = 8748528
59 + 8748469 = 8748528
97 + 8748431 = 8748528
109 + 8748419 = 8748528
167 + 8748361 = 8748528
197 + 8748331 = 8748528
199 + 8748329 = 8748528
241 + 8748287 = 8748528

Showing the first eight; more decompositions exist.
