Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490784, here are decompositions:

13 + 490771 = 490784
43 + 490741 = 490784
157 + 490627 = 490784
193 + 490591 = 490784
211 + 490573 = 490784
241 + 490543 = 490784
331 + 490453 = 490784
367 + 490417 = 490784

Showing the first eight; more decompositions exist.
