Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51422, here are decompositions:

3 + 51419 = 51422
61 + 51361 = 51422
73 + 51349 = 51422
79 + 51343 = 51422
139 + 51283 = 51422
181 + 51241 = 51422
193 + 51229 = 51422
223 + 51199 = 51422

Showing the first eight; more decompositions exist.
