Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002178, here are decompositions:

5 + 1002173 = 1002178
29 + 1002149 = 1002178
101 + 1002077 = 1002178
197 + 1001981 = 1002178
347 + 1001831 = 1002178
491 + 1001687 = 1002178
509 + 1001669 = 1002178
557 + 1001621 = 1002178

Showing the first eight; more decompositions exist.
