Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535820, here are decompositions:

37 + 535783 = 535820
79 + 535741 = 535820
151 + 535669 = 535820
157 + 535663 = 535820
193 + 535627 = 535820
211 + 535609 = 535820
331 + 535489 = 535820
421 + 535399 = 535820

Showing the first eight; more decompositions exist.
