Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523180, here are decompositions:

3 + 523177 = 523180
11 + 523169 = 523180
71 + 523109 = 523180
83 + 523097 = 523180
131 + 523049 = 523180
149 + 523031 = 523180
173 + 523007 = 523180
191 + 522989 = 523180

Showing the first eight; more decompositions exist.
