Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523786, here are decompositions:

23 + 523763 = 523786
113 + 523673 = 523786
149 + 523637 = 523786
233 + 523553 = 523786
293 + 523493 = 523786
353 + 523433 = 523786
359 + 523427 = 523786
383 + 523403 = 523786

Showing the first eight; more decompositions exist.
