Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748506, here are decompositions:

3 + 8748503 = 8748506
7 + 8748499 = 8748506
37 + 8748469 = 8748506
43 + 8748463 = 8748506
103 + 8748403 = 8748506
139 + 8748367 = 8748506
229 + 8748277 = 8748506
307 + 8748199 = 8748506

Showing the first eight; more decompositions exist.
