Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742924, here are decompositions:

5 + 8742919 = 8742924
7 + 8742917 = 8742924
37 + 8742887 = 8742924
67 + 8742857 = 8742924
103 + 8742821 = 8742924
107 + 8742817 = 8742924
137 + 8742787 = 8742924
251 + 8742673 = 8742924

Showing the first eight; more decompositions exist.
