Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747984, here are decompositions:

13 + 8747971 = 8747984
43 + 8747941 = 8747984
67 + 8747917 = 8747984
127 + 8747857 = 8747984
181 + 8747803 = 8747984
241 + 8747743 = 8747984
283 + 8747701 = 8747984
307 + 8747677 = 8747984

Showing the first eight; more decompositions exist.
