Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523170, here are decompositions:

41 + 523129 = 523170
61 + 523109 = 523170
73 + 523097 = 523170
139 + 523031 = 523170
149 + 523021 = 523170
163 + 523007 = 523170
181 + 522989 = 523170
211 + 522959 = 523170

Showing the first eight; more decompositions exist.
