Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002886, here are decompositions:

23 + 1002863 = 1002886
29 + 1002857 = 1002886
89 + 1002797 = 1002886
113 + 1002773 = 1002886
167 + 1002719 = 1002886
173 + 1002713 = 1002886
233 + 1002653 = 1002886
239 + 1002647 = 1002886

Showing the first eight; more decompositions exist.
