Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43072, here are decompositions:

5 + 43067 = 43072
23 + 43049 = 43072
53 + 43019 = 43072
59 + 43013 = 43072
83 + 42989 = 43072
149 + 42923 = 43072
173 + 42899 = 43072
233 + 42839 = 43072

Showing the first eight; more decompositions exist.
