Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523138, here are decompositions:

29 + 523109 = 523138
41 + 523097 = 523138
89 + 523049 = 523138
107 + 523031 = 523138
131 + 523007 = 523138
149 + 522989 = 523138
179 + 522959 = 523138
191 + 522947 = 523138

Showing the first eight; more decompositions exist.
