Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51628, here are decompositions:

29 + 51599 = 51628
47 + 51581 = 51628
89 + 51539 = 51628
107 + 51521 = 51628
149 + 51479 = 51628
167 + 51461 = 51628
179 + 51449 = 51628
191 + 51437 = 51628

Showing the first eight; more decompositions exist.
