Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20144, here are decompositions:

31 + 20113 = 20144
37 + 20107 = 20144
43 + 20101 = 20144
73 + 20071 = 20144
97 + 20047 = 20144
151 + 19993 = 20144
181 + 19963 = 20144
277 + 19867 = 20144

Showing the first eight; more decompositions exist.
