Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499420, here are decompositions:

17 + 499403 = 499420
23 + 499397 = 499420
29 + 499391 = 499420
59 + 499361 = 499420
71 + 499349 = 499420
137 + 499283 = 499420
167 + 499253 = 499420
191 + 499229 = 499420

Showing the first eight; more decompositions exist.
