Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490880, here are decompositions:

3 + 490877 = 490880
31 + 490849 = 490880
43 + 490837 = 490880
97 + 490783 = 490880
109 + 490771 = 490880
139 + 490741 = 490880
307 + 490573 = 490880
331 + 490549 = 490880

Showing the first eight; more decompositions exist.
