Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53990, here are decompositions:

3 + 53987 = 53990
31 + 53959 = 53990
67 + 53923 = 53990
73 + 53917 = 53990
103 + 53887 = 53990
109 + 53881 = 53990
199 + 53791 = 53990
271 + 53719 = 53990

Showing the first eight; more decompositions exist.
