Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747970, here are decompositions:

13 + 8747957 = 8747970
29 + 8747941 = 8747970
37 + 8747933 = 8747970
41 + 8747929 = 8747970
43 + 8747927 = 8747970
53 + 8747917 = 8747970
67 + 8747903 = 8747970
79 + 8747891 = 8747970

Showing the first eight; more decompositions exist.
