Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523586, here are decompositions:

13 + 523573 = 523586
43 + 523543 = 523586
67 + 523519 = 523586
97 + 523489 = 523586
127 + 523459 = 523586
199 + 523387 = 523586
229 + 523357 = 523586
367 + 523219 = 523586

Showing the first eight; more decompositions exist.
