Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019804, here are decompositions:

3 + 1019801 = 1019804
73 + 1019731 = 1019804
103 + 1019701 = 1019804
157 + 1019647 = 1019804
241 + 1019563 = 1019804
271 + 1019533 = 1019804
337 + 1019467 = 1019804
523 + 1019281 = 1019804

Showing the first eight; more decompositions exist.
