Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61216, here are decompositions:

5 + 61211 = 61216
47 + 61169 = 61216
173 + 61043 = 61216
263 + 60953 = 61216
293 + 60923 = 61216
317 + 60899 = 61216
347 + 60869 = 61216
443 + 60773 = 61216

Showing the first eight; more decompositions exist.
