Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43990, here are decompositions:

3 + 43987 = 43990
17 + 43973 = 43990
29 + 43961 = 43990
47 + 43943 = 43990
101 + 43889 = 43990
137 + 43853 = 43990
197 + 43793 = 43990
269 + 43721 = 43990

Showing the first eight; more decompositions exist.
