Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742894, here are decompositions:

7 + 8742887 = 8742894
37 + 8742857 = 8742894
47 + 8742847 = 8742894
73 + 8742821 = 8742894
107 + 8742787 = 8742894
241 + 8742653 = 8742894
257 + 8742637 = 8742894
271 + 8742623 = 8742894

Showing the first eight; more decompositions exist.
