Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001630, here are decompositions:

37 + 1001593 = 1001630
43 + 1001587 = 1001630
61 + 1001569 = 1001630
67 + 1001563 = 1001630
79 + 1001551 = 1001630
103 + 1001527 = 1001630
139 + 1001491 = 1001630
163 + 1001467 = 1001630

Showing the first eight; more decompositions exist.
