Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523912, here are decompositions:

5 + 523907 = 523912
83 + 523829 = 523912
149 + 523763 = 523912
239 + 523673 = 523912
281 + 523631 = 523912
359 + 523553 = 523912
401 + 523511 = 523912
419 + 523493 = 523912

Showing the first eight; more decompositions exist.
