Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523856, here are decompositions:

79 + 523777 = 523856
97 + 523759 = 523856
127 + 523729 = 523856
139 + 523717 = 523856
199 + 523657 = 523856
283 + 523573 = 523856
313 + 523543 = 523856
337 + 523519 = 523856

Showing the first eight; more decompositions exist.
