Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523658, here are decompositions:

19 + 523639 = 523658
61 + 523597 = 523658
139 + 523519 = 523658
199 + 523459 = 523658
241 + 523417 = 523658
271 + 523387 = 523658
307 + 523351 = 523658
397 + 523261 = 523658

Showing the first eight; more decompositions exist.
