Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527580, here are decompositions:

17 + 527563 = 527580
23 + 527557 = 527580
47 + 527533 = 527580
73 + 527507 = 527580
127 + 527453 = 527580
139 + 527441 = 527580
173 + 527407 = 527580
181 + 527399 = 527580

Showing the first eight; more decompositions exist.
