Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499894, here are decompositions:

11 + 499883 = 499894
41 + 499853 = 499894
107 + 499787 = 499894
113 + 499781 = 499894
233 + 499661 = 499894
257 + 499637 = 499894
293 + 499601 = 499894
401 + 499493 = 499894

Showing the first eight; more decompositions exist.
