Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523390, here are decompositions:

3 + 523387 = 523390
41 + 523349 = 523390
83 + 523307 = 523390
281 + 523109 = 523390
293 + 523097 = 523390
359 + 523031 = 523390
383 + 523007 = 523390
401 + 522989 = 523390

Showing the first eight; more decompositions exist.
