Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61720, here are decompositions:

3 + 61717 = 61720
17 + 61703 = 61720
47 + 61673 = 61720
53 + 61667 = 61720
83 + 61637 = 61720
89 + 61631 = 61720
107 + 61613 = 61720
137 + 61583 = 61720

Showing the first eight; more decompositions exist.
