Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747894, here are decompositions:

3 + 8747891 = 8747894
31 + 8747863 = 8747894
37 + 8747857 = 8747894
151 + 8747743 = 8747894
157 + 8747737 = 8747894
193 + 8747701 = 8747894
241 + 8747653 = 8747894
271 + 8747623 = 8747894

Showing the first eight; more decompositions exist.
