Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61988, here are decompositions:

7 + 61981 = 61988
61 + 61927 = 61988
79 + 61909 = 61988
109 + 61879 = 61988
127 + 61861 = 61988
151 + 61837 = 61988
271 + 61717 = 61988
307 + 61681 = 61988

Showing the first eight; more decompositions exist.
