Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000888, here are decompositions:

29 + 1000859 = 1000888
41 + 1000847 = 1000888
59 + 1000829 = 1000888
167 + 1000721 = 1000888
191 + 1000697 = 1000888
197 + 1000691 = 1000888
269 + 1000619 = 1000888
311 + 1000577 = 1000888

Showing the first eight; more decompositions exist.
