Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488818, here are decompositions:

59 + 488759 = 488818
89 + 488729 = 488818
101 + 488717 = 488818
107 + 488711 = 488818
131 + 488687 = 488818
167 + 488651 = 488818
179 + 488639 = 488818
191 + 488627 = 488818

Showing the first eight; more decompositions exist.
