Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523378, here are decompositions:

29 + 523349 = 523378
71 + 523307 = 523378
269 + 523109 = 523378
281 + 523097 = 523378
347 + 523031 = 523378
389 + 522989 = 523378
419 + 522959 = 523378
431 + 522947 = 523378

Showing the first eight; more decompositions exist.
