Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523402, here are decompositions:

53 + 523349 = 523402
233 + 523169 = 523402
293 + 523109 = 523402
353 + 523049 = 523402
443 + 522959 = 523402
521 + 522881 = 523402
563 + 522839 = 523402
641 + 522761 = 523402

Showing the first eight; more decompositions exist.
