Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499440, here are decompositions:

17 + 499423 = 499440
37 + 499403 = 499440
43 + 499397 = 499440
79 + 499361 = 499440
113 + 499327 = 499440
131 + 499309 = 499440
157 + 499283 = 499440
163 + 499277 = 499440

Showing the first eight; more decompositions exist.
