Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490582, here are decompositions:

3 + 490579 = 490582
5 + 490577 = 490582
11 + 490571 = 490582
23 + 490559 = 490582
41 + 490541 = 490582
83 + 490499 = 490582
89 + 490493 = 490582
101 + 490481 = 490582

Showing the first eight; more decompositions exist.
