Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61818, here are decompositions:

5 + 61813 = 61818
37 + 61781 = 61818
61 + 61757 = 61818
67 + 61751 = 61818
89 + 61729 = 61818
101 + 61717 = 61818
131 + 61687 = 61818
137 + 61681 = 61818

Showing the first eight; more decompositions exist.
