Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490836, here are decompositions:

7 + 490829 = 490836
53 + 490783 = 490836
67 + 490769 = 490836
103 + 490733 = 490836
139 + 490697 = 490836
173 + 490663 = 490836
193 + 490643 = 490836
257 + 490579 = 490836

Showing the first eight; more decompositions exist.
