Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041820, here are decompositions:

41 + 1041779 = 1041820
83 + 1041737 = 1041820
89 + 1041731 = 1041820
149 + 1041671 = 1041820
167 + 1041653 = 1041820
257 + 1041563 = 1041820
359 + 1041461 = 1041820
491 + 1041329 = 1041820

Showing the first eight; more decompositions exist.
