Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61986, here are decompositions:

5 + 61981 = 61986
7 + 61979 = 61986
19 + 61967 = 61986
37 + 61949 = 61986
53 + 61933 = 61986
59 + 61927 = 61986
107 + 61879 = 61986
149 + 61837 = 61986

Showing the first eight; more decompositions exist.
