Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43128, here are decompositions:

11 + 43117 = 43128
61 + 43067 = 43128
79 + 43049 = 43128
109 + 43019 = 43128
139 + 42989 = 43128
149 + 42979 = 43128
167 + 42961 = 43128
191 + 42937 = 43128

Showing the first eight; more decompositions exist.
