Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742948, here are decompositions:

7 + 8742941 = 8742948
17 + 8742931 = 8742948
29 + 8742919 = 8742948
31 + 8742917 = 8742948
61 + 8742887 = 8742948
101 + 8742847 = 8742948
127 + 8742821 = 8742948
131 + 8742817 = 8742948

Showing the first eight; more decompositions exist.
