Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490654, here are decompositions:

11 + 490643 = 490654
23 + 490631 = 490654
83 + 490571 = 490654
113 + 490541 = 490654
173 + 490481 = 490654
191 + 490463 = 490654
233 + 490421 = 490654
383 + 490271 = 490654

Showing the first eight; more decompositions exist.
