Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499648, here are decompositions:

11 + 499637 = 499648
41 + 499607 = 499648
47 + 499601 = 499648
89 + 499559 = 499648
167 + 499481 = 499648
251 + 499397 = 499648
257 + 499391 = 499648
419 + 499229 = 499648

Showing the first eight; more decompositions exist.
