Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521732, here are decompositions:

61 + 521671 = 521732
73 + 521659 = 521732
151 + 521581 = 521732
181 + 521551 = 521732
193 + 521539 = 521732
199 + 521533 = 521732
229 + 521503 = 521732
241 + 521491 = 521732

Showing the first eight; more decompositions exist.
