Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61686, here are decompositions:

5 + 61681 = 61686
13 + 61673 = 61686
19 + 61667 = 61686
29 + 61657 = 61686
43 + 61643 = 61686
59 + 61627 = 61686
73 + 61613 = 61686
83 + 61603 = 61686

Showing the first eight; more decompositions exist.
