Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523780, here are decompositions:

3 + 523777 = 523780
17 + 523763 = 523780
107 + 523673 = 523780
113 + 523667 = 523780
149 + 523631 = 523780
227 + 523553 = 523780
239 + 523541 = 523780
269 + 523511 = 523780

Showing the first eight; more decompositions exist.
