Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523578, here are decompositions:

5 + 523573 = 523578
7 + 523571 = 523578
37 + 523541 = 523578
59 + 523519 = 523578
67 + 523511 = 523578
89 + 523489 = 523578
151 + 523427 = 523578
191 + 523387 = 523578

Showing the first eight; more decompositions exist.
