Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008650, here are decompositions:

37 + 1008613 = 1008650
43 + 1008607 = 1008650
61 + 1008589 = 1008650
79 + 1008571 = 1008650
103 + 1008547 = 1008650
109 + 1008541 = 1008650
151 + 1008499 = 1008650
157 + 1008493 = 1008650

Showing the first eight; more decompositions exist.
