Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43038, here are decompositions:

19 + 43019 = 43038
59 + 42979 = 43038
71 + 42967 = 43038
101 + 42937 = 43038
109 + 42929 = 43038
137 + 42901 = 43038
139 + 42899 = 43038
179 + 42859 = 43038

Showing the first eight; more decompositions exist.
