Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747994, here are decompositions:

7 + 8747987 = 8747994
23 + 8747971 = 8747994
37 + 8747957 = 8747994
53 + 8747941 = 8747994
61 + 8747933 = 8747994
67 + 8747927 = 8747994
103 + 8747891 = 8747994
131 + 8747863 = 8747994

Showing the first eight; more decompositions exist.
