Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747964, here are decompositions:

7 + 8747957 = 8747964
23 + 8747941 = 8747964
31 + 8747933 = 8747964
37 + 8747927 = 8747964
47 + 8747917 = 8747964
61 + 8747903 = 8747964
73 + 8747891 = 8747964
101 + 8747863 = 8747964

Showing the first eight; more decompositions exist.
