Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61678, here are decompositions:

5 + 61673 = 61678
11 + 61667 = 61678
41 + 61637 = 61678
47 + 61631 = 61678
131 + 61547 = 61678
167 + 61511 = 61678
191 + 61487 = 61678
269 + 61409 = 61678

Showing the first eight; more decompositions exist.
