Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490900, here are decompositions:

23 + 490877 = 490900
41 + 490859 = 490900
71 + 490829 = 490900
131 + 490769 = 490900
167 + 490733 = 490900
239 + 490661 = 490900
257 + 490643 = 490900
269 + 490631 = 490900

Showing the first eight; more decompositions exist.
