Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51988, here are decompositions:

11 + 51977 = 51988
17 + 51971 = 51988
47 + 51941 = 51988
59 + 51929 = 51988
89 + 51899 = 51988
149 + 51839 = 51988
191 + 51797 = 51988
239 + 51749 = 51988

Showing the first eight; more decompositions exist.
