Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1036820, here are decompositions:

61 + 1036759 = 1036820
73 + 1036747 = 1036820
139 + 1036681 = 1036820
151 + 1036669 = 1036820
241 + 1036579 = 1036820
283 + 1036537 = 1036820
307 + 1036513 = 1036820
349 + 1036471 = 1036820

Showing the first eight; more decompositions exist.
