Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61280, here are decompositions:

19 + 61261 = 61280
127 + 61153 = 61280
139 + 61141 = 61280
151 + 61129 = 61280
181 + 61099 = 61280
223 + 61057 = 61280
229 + 61051 = 61280
337 + 60943 = 61280

Showing the first eight; more decompositions exist.
