Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002142, here are decompositions:

41 + 1002101 = 1002142
59 + 1002083 = 1002142
311 + 1001831 = 1002142
359 + 1001783 = 1002142
419 + 1001723 = 1002142
503 + 1001639 = 1002142
521 + 1001621 = 1002142
593 + 1001549 = 1002142

Showing the first eight; more decompositions exist.
