Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51406, here are decompositions:

23 + 51383 = 51406
59 + 51347 = 51406
149 + 51257 = 51406
167 + 51239 = 51406
269 + 51137 = 51406
347 + 51059 = 51406
359 + 51047 = 51406
449 + 50957 = 51406

Showing the first eight; more decompositions exist.
