Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42280, here are decompositions:

23 + 42257 = 42280
41 + 42239 = 42280
53 + 42227 = 42280
59 + 42221 = 42280
71 + 42209 = 42280
83 + 42197 = 42280
101 + 42179 = 42280
149 + 42131 = 42280

Showing the first eight; more decompositions exist.
