Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501648, here are decompositions:

11 + 501637 = 501648
31 + 501617 = 501648
47 + 501601 = 501648
71 + 501577 = 501648
137 + 501511 = 501648
197 + 501451 = 501648
229 + 501419 = 501648
239 + 501409 = 501648

Showing the first eight; more decompositions exist.
