Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532820, here are decompositions:

19 + 532801 = 532820
31 + 532789 = 532820
37 + 532783 = 532820
151 + 532669 = 532820
157 + 532663 = 532820
181 + 532639 = 532820
199 + 532621 = 532820
283 + 532537 = 532820

Showing the first eight; more decompositions exist.
