Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523618, here are decompositions:

41 + 523577 = 523618
47 + 523571 = 523618
107 + 523511 = 523618
131 + 523487 = 523618
191 + 523427 = 523618
269 + 523349 = 523618
311 + 523307 = 523618
449 + 523169 = 523618

Showing the first eight; more decompositions exist.
