Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523500, here are decompositions:

7 + 523493 = 523500
11 + 523489 = 523500
13 + 523487 = 523500
37 + 523463 = 523500
41 + 523459 = 523500
67 + 523433 = 523500
73 + 523427 = 523500
83 + 523417 = 523500

Showing the first eight; more decompositions exist.
