Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523258, here are decompositions:

89 + 523169 = 523258
149 + 523109 = 523258
227 + 523031 = 523258
251 + 523007 = 523258
269 + 522989 = 523258
311 + 522947 = 523258
401 + 522857 = 523258
419 + 522839 = 523258

Showing the first eight; more decompositions exist.
