Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523526, here are decompositions:

7 + 523519 = 523526
37 + 523489 = 523526
67 + 523459 = 523526
109 + 523417 = 523526
139 + 523387 = 523526
193 + 523333 = 523526
229 + 523297 = 523526
307 + 523219 = 523526

Showing the first eight; more decompositions exist.
