Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523580, here are decompositions:

3 + 523577 = 523580
7 + 523573 = 523580
37 + 523543 = 523580
61 + 523519 = 523580
163 + 523417 = 523580
193 + 523387 = 523580
223 + 523357 = 523580
229 + 523351 = 523580

Showing the first eight; more decompositions exist.
