Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61810, here are decompositions:

29 + 61781 = 61810
53 + 61757 = 61810
59 + 61751 = 61810
107 + 61703 = 61810
137 + 61673 = 61810
167 + 61643 = 61810
173 + 61637 = 61810
179 + 61631 = 61810

Showing the first eight; more decompositions exist.
