Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470172, here are decompositions:

5 + 470167 = 470172
11 + 470161 = 470172
19 + 470153 = 470172
23 + 470149 = 470172
41 + 470131 = 470172
83 + 470089 = 470172
89 + 470083 = 470172
113 + 470059 = 470172

Showing the first eight; more decompositions exist.
