Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523726, here are decompositions:

53 + 523673 = 523726
59 + 523667 = 523726
89 + 523637 = 523726
149 + 523577 = 523726
173 + 523553 = 523726
233 + 523493 = 523726
239 + 523487 = 523726
263 + 523463 = 523726

Showing the first eight; more decompositions exist.
