Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523172, here are decompositions:

3 + 523169 = 523172
43 + 523129 = 523172
79 + 523093 = 523172
151 + 523021 = 523172
211 + 522961 = 523172
229 + 522943 = 523172
409 + 522763 = 523172
499 + 522673 = 523172

Showing the first eight; more decompositions exist.
