Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002942, here are decompositions:

11 + 1002931 = 1002942
13 + 1002929 = 1002942
29 + 1002913 = 1002942
43 + 1002899 = 1002942
71 + 1002871 = 1002942
79 + 1002863 = 1002942
89 + 1002853 = 1002942
173 + 1002769 = 1002942

Showing the first eight; more decompositions exist.
