Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61864, here are decompositions:

3 + 61861 = 61864
83 + 61781 = 61864
107 + 61757 = 61864
113 + 61751 = 61864
191 + 61673 = 61864
197 + 61667 = 61864
227 + 61637 = 61864
233 + 61631 = 61864

Showing the first eight; more decompositions exist.
