Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61900, here are decompositions:

29 + 61871 = 61900
149 + 61751 = 61900
197 + 61703 = 61900
227 + 61673 = 61900
233 + 61667 = 61900
257 + 61643 = 61900
263 + 61637 = 61900
269 + 61631 = 61900

Showing the first eight; more decompositions exist.
