Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488730, here are decompositions:

7 + 488723 = 488730
13 + 488717 = 488730
19 + 488711 = 488730
29 + 488701 = 488730
41 + 488689 = 488730
43 + 488687 = 488730
79 + 488651 = 488730
89 + 488641 = 488730

Showing the first eight; more decompositions exist.
