Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499658, here are decompositions:

37 + 499621 = 499658
67 + 499591 = 499658
109 + 499549 = 499658
139 + 499519 = 499658
151 + 499507 = 499658
199 + 499459 = 499658
331 + 499327 = 499658
337 + 499321 = 499658

Showing the first eight; more decompositions exist.
