Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523688, here are decompositions:

7 + 523681 = 523688
19 + 523669 = 523688
31 + 523657 = 523688
199 + 523489 = 523688
229 + 523459 = 523688
271 + 523417 = 523688
331 + 523357 = 523688
337 + 523351 = 523688

Showing the first eight; more decompositions exist.
