Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523128, here are decompositions:

19 + 523109 = 523128
31 + 523097 = 523128
79 + 523049 = 523128
97 + 523031 = 523128
107 + 523021 = 523128
139 + 522989 = 523128
167 + 522961 = 523128
181 + 522947 = 523128

Showing the first eight; more decompositions exist.
