Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508648, here are decompositions:

5 + 508643 = 508648
11 + 508637 = 508648
29 + 508619 = 508648
71 + 508577 = 508648
89 + 508559 = 508648
131 + 508517 = 508648
149 + 508499 = 508648
197 + 508451 = 508648

Showing the first eight; more decompositions exist.
