Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748478, here are decompositions:

5 + 8748473 = 8748478
47 + 8748431 = 8748478
59 + 8748419 = 8748478
149 + 8748329 = 8748478
191 + 8748287 = 8748478
197 + 8748281 = 8748478
269 + 8748209 = 8748478
311 + 8748167 = 8748478

Showing the first eight; more decompositions exist.
