Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61978, here are decompositions:

11 + 61967 = 61978
17 + 61961 = 61978
29 + 61949 = 61978
107 + 61871 = 61978
197 + 61781 = 61978
227 + 61751 = 61978
311 + 61667 = 61978
347 + 61631 = 61978

Showing the first eight; more decompositions exist.
