Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486818, here are decompositions:

37 + 486781 = 486818
61 + 486757 = 486818
97 + 486721 = 486818
139 + 486679 = 486818
151 + 486667 = 486818
181 + 486637 = 486818
229 + 486589 = 486818
307 + 486511 = 486818

Showing the first eight; more decompositions exist.
