Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61786, here are decompositions:

5 + 61781 = 61786
29 + 61757 = 61786
83 + 61703 = 61786
113 + 61673 = 61786
149 + 61637 = 61786
173 + 61613 = 61786
227 + 61559 = 61786
233 + 61553 = 61786

Showing the first eight; more decompositions exist.
