Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488790, here are decompositions:

11 + 488779 = 488790
31 + 488759 = 488790
41 + 488749 = 488790
47 + 488743 = 488790
61 + 488729 = 488790
67 + 488723 = 488790
73 + 488717 = 488790
79 + 488711 = 488790

Showing the first eight; more decompositions exist.
