Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490918, here are decompositions:

5 + 490913 = 490918
41 + 490877 = 490918
59 + 490859 = 490918
89 + 490829 = 490918
149 + 490769 = 490918
257 + 490661 = 490918
347 + 490571 = 490918
359 + 490559 = 490918

Showing the first eight; more decompositions exist.
