Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488740, here are decompositions:

11 + 488729 = 488740
17 + 488723 = 488740
23 + 488717 = 488740
29 + 488711 = 488740
53 + 488687 = 488740
89 + 488651 = 488740
101 + 488639 = 488740
107 + 488633 = 488740

Showing the first eight; more decompositions exist.
