Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019984, here are decompositions:

13 + 1019971 = 1019984
127 + 1019857 = 1019984
157 + 1019827 = 1019984
271 + 1019713 = 1019984
283 + 1019701 = 1019984
337 + 1019647 = 1019984
367 + 1019617 = 1019984
421 + 1019563 = 1019984

Showing the first eight; more decompositions exist.
