Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488772, here are decompositions:

13 + 488759 = 488772
23 + 488749 = 488772
29 + 488743 = 488772
43 + 488729 = 488772
61 + 488711 = 488772
71 + 488701 = 488772
83 + 488689 = 488772
131 + 488641 = 488772

Showing the first eight; more decompositions exist.
