Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747960, here are decompositions:

3 + 8747957 = 8747960
19 + 8747941 = 8747960
31 + 8747929 = 8747960
43 + 8747917 = 8747960
97 + 8747863 = 8747960
103 + 8747857 = 8747960
157 + 8747803 = 8747960
223 + 8747737 = 8747960

Showing the first eight; more decompositions exist.
