Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13990, here are decompositions:

23 + 13967 = 13990
59 + 13931 = 13990
83 + 13907 = 13990
89 + 13901 = 13990
107 + 13883 = 13990
113 + 13877 = 13990
131 + 13859 = 13990
149 + 13841 = 13990

Showing the first eight; more decompositions exist.
