Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002888, here are decompositions:

17 + 1002871 = 1002888
31 + 1002857 = 1002888
37 + 1002851 = 1002888
67 + 1002821 = 1002888
71 + 1002817 = 1002888
79 + 1002809 = 1002888
101 + 1002787 = 1002888
137 + 1002751 = 1002888

Showing the first eight; more decompositions exist.
