Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002986, here are decompositions:

7 + 1002979 = 1002986
13 + 1002973 = 1002986
73 + 1002913 = 1002986
199 + 1002787 = 1002986
277 + 1002709 = 1002986
307 + 1002679 = 1002986
367 + 1002619 = 1002986
409 + 1002577 = 1002986

Showing the first eight; more decompositions exist.
