Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747864, here are decompositions:

7 + 8747857 = 8747864
61 + 8747803 = 8747864
127 + 8747737 = 8747864
163 + 8747701 = 8747864
211 + 8747653 = 8747864
241 + 8747623 = 8747864
337 + 8747527 = 8747864
457 + 8747407 = 8747864

Showing the first eight; more decompositions exist.
