Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61980, here are decompositions:

13 + 61967 = 61980
19 + 61961 = 61980
31 + 61949 = 61980
47 + 61933 = 61980
53 + 61927 = 61980
71 + 61909 = 61980
101 + 61879 = 61980
109 + 61871 = 61980

Showing the first eight; more decompositions exist.
