Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748378, here are decompositions:

11 + 8748367 = 8748378
17 + 8748361 = 8748378
19 + 8748359 = 8748378
47 + 8748331 = 8748378
97 + 8748281 = 8748378
101 + 8748277 = 8748378
179 + 8748199 = 8748378
211 + 8748167 = 8748378

Showing the first eight; more decompositions exist.
