Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499090, here are decompositions:

23 + 499067 = 499090
101 + 498989 = 499090
113 + 498977 = 499090
167 + 498923 = 499090
233 + 498857 = 499090
257 + 498833 = 499090
311 + 498779 = 499090
401 + 498689 = 499090

Showing the first eight; more decompositions exist.
