Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523146, here are decompositions:

17 + 523129 = 523146
37 + 523109 = 523146
53 + 523093 = 523146
97 + 523049 = 523146
139 + 523007 = 523146
157 + 522989 = 523146
199 + 522947 = 523146
227 + 522919 = 523146

Showing the first eight; more decompositions exist.
