Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019894, here are decompositions:

37 + 1019857 = 1019894
67 + 1019827 = 1019894
163 + 1019731 = 1019894
181 + 1019713 = 1019894
193 + 1019701 = 1019894
277 + 1019617 = 1019894
331 + 1019563 = 1019894
541 + 1019353 = 1019894

Showing the first eight; more decompositions exist.
