Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523450, here are decompositions:

17 + 523433 = 523450
23 + 523427 = 523450
47 + 523403 = 523450
101 + 523349 = 523450
281 + 523169 = 523450
353 + 523097 = 523450
401 + 523049 = 523450
419 + 523031 = 523450

Showing the first eight; more decompositions exist.
