Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53986, here are decompositions:

47 + 53939 = 53986
59 + 53927 = 53986
89 + 53897 = 53986
137 + 53849 = 53986
167 + 53819 = 53986
173 + 53813 = 53986
227 + 53759 = 53986
269 + 53717 = 53986

Showing the first eight; more decompositions exist.
