Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499644, here are decompositions:

7 + 499637 = 499644
11 + 499633 = 499644
23 + 499621 = 499644
37 + 499607 = 499644
43 + 499601 = 499644
53 + 499591 = 499644
73 + 499571 = 499644
137 + 499507 = 499644

Showing the first eight; more decompositions exist.
