Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009178, here are decompositions:

19 + 1009159 = 1009178
199 + 1008979 = 1009178
241 + 1008937 = 1009178
277 + 1008901 = 1009178
307 + 1008871 = 1009178
349 + 1008829 = 1009178
397 + 1008781 = 1009178
571 + 1008607 = 1009178

Showing the first eight; more decompositions exist.
