Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472128, here are decompositions:

5 + 472123 = 472128
17 + 472111 = 472128
61 + 472067 = 472128
71 + 472057 = 472128
101 + 472027 = 472128
109 + 472019 = 472128
131 + 471997 = 472128
179 + 471949 = 472128

Showing the first eight; more decompositions exist.
