Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490942, here are decompositions:

5 + 490937 = 490942
29 + 490913 = 490942
83 + 490859 = 490942
113 + 490829 = 490942
173 + 490769 = 490942
281 + 490661 = 490942
311 + 490631 = 490942
383 + 490559 = 490942

Showing the first eight; more decompositions exist.
