Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490798, here are decompositions:

29 + 490769 = 490798
101 + 490697 = 490798
137 + 490661 = 490798
167 + 490631 = 490798
179 + 490619 = 490798
227 + 490571 = 490798
239 + 490559 = 490798
257 + 490541 = 490798

Showing the first eight; more decompositions exist.
