Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002442, here are decompositions:

83 + 1002359 = 1002442
101 + 1002341 = 1002442
179 + 1002263 = 1002442
251 + 1002191 = 1002442
269 + 1002173 = 1002442
293 + 1002149 = 1002442
359 + 1002083 = 1002442
461 + 1001981 = 1002442

Showing the first eight; more decompositions exist.
