Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748340, here are decompositions:

11 + 8748329 = 8748340
17 + 8748323 = 8748340
53 + 8748287 = 8748340
59 + 8748281 = 8748340
131 + 8748209 = 8748340
137 + 8748203 = 8748340
149 + 8748191 = 8748340
173 + 8748167 = 8748340

Showing the first eight; more decompositions exist.
