Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490946, here are decompositions:

19 + 490927 = 490946
97 + 490849 = 490946
109 + 490837 = 490946
163 + 490783 = 490946
283 + 490663 = 490946
367 + 490579 = 490946
373 + 490573 = 490946
397 + 490549 = 490946

Showing the first eight; more decompositions exist.
