Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523528, here are decompositions:

17 + 523511 = 523528
41 + 523487 = 523528
101 + 523427 = 523528
179 + 523349 = 523528
359 + 523169 = 523528
419 + 523109 = 523528
431 + 523097 = 523528
479 + 523049 = 523528

Showing the first eight; more decompositions exist.
