Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490906, here are decompositions:

29 + 490877 = 490906
47 + 490859 = 490906
137 + 490769 = 490906
173 + 490733 = 490906
263 + 490643 = 490906
347 + 490559 = 490906
443 + 490463 = 490906
593 + 490313 = 490906

Showing the first eight; more decompositions exist.
