Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499858, here are decompositions:

5 + 499853 = 499858
71 + 499787 = 499858
167 + 499691 = 499858
179 + 499679 = 499858
197 + 499661 = 499858
251 + 499607 = 499858
257 + 499601 = 499858
419 + 499439 = 499858

Showing the first eight; more decompositions exist.
