Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43040, here are decompositions:

3 + 43037 = 43040
37 + 43003 = 43040
61 + 42979 = 43040
73 + 42967 = 43040
79 + 42961 = 43040
97 + 42943 = 43040
103 + 42937 = 43040
139 + 42901 = 43040

Showing the first eight; more decompositions exist.
