Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523506, here are decompositions:

13 + 523493 = 523506
17 + 523489 = 523506
19 + 523487 = 523506
43 + 523463 = 523506
47 + 523459 = 523506
73 + 523433 = 523506
79 + 523427 = 523506
89 + 523417 = 523506

Showing the first eight; more decompositions exist.
