Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1035820, here are decompositions:

29 + 1035791 = 1035820
59 + 1035761 = 1035820
113 + 1035707 = 1035820
179 + 1035641 = 1035820
239 + 1035581 = 1035820
257 + 1035563 = 1035820
293 + 1035527 = 1035820
347 + 1035473 = 1035820

Showing the first eight; more decompositions exist.
