Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61660, here are decompositions:

3 + 61657 = 61660
17 + 61643 = 61660
23 + 61637 = 61660
29 + 61631 = 61660
47 + 61613 = 61660
101 + 61559 = 61660
107 + 61553 = 61660
113 + 61547 = 61660

Showing the first eight; more decompositions exist.
