Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490744, here are decompositions:

3 + 490741 = 490744
11 + 490733 = 490744
47 + 490697 = 490744
83 + 490661 = 490744
101 + 490643 = 490744
113 + 490631 = 490744
167 + 490577 = 490744
173 + 490571 = 490744

Showing the first eight; more decompositions exist.
