Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490858, here are decompositions:

29 + 490829 = 490858
89 + 490769 = 490858
197 + 490661 = 490858
227 + 490631 = 490858
239 + 490619 = 490858
281 + 490577 = 490858
317 + 490541 = 490858
359 + 490499 = 490858

Showing the first eight; more decompositions exist.
