Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499388, here are decompositions:

61 + 499327 = 499388
67 + 499321 = 499388
79 + 499309 = 499388
199 + 499189 = 499388
229 + 499159 = 499388
271 + 499117 = 499388
349 + 499039 = 499388
367 + 499021 = 499388

Showing the first eight; more decompositions exist.
