Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523290, here are decompositions:

29 + 523261 = 523290
71 + 523219 = 523290
83 + 523207 = 523290
113 + 523177 = 523290
181 + 523109 = 523290
193 + 523097 = 523290
197 + 523093 = 523290
241 + 523049 = 523290

Showing the first eight; more decompositions exist.
