Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498990, here are decompositions:

13 + 498977 = 498990
17 + 498973 = 498990
29 + 498961 = 498990
43 + 498947 = 498990
53 + 498937 = 498990
59 + 498931 = 498990
67 + 498923 = 498990
83 + 498907 = 498990

Showing the first eight; more decompositions exist.
