Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747924, here are decompositions:

7 + 8747917 = 8747924
61 + 8747863 = 8747924
67 + 8747857 = 8747924
181 + 8747743 = 8747924
223 + 8747701 = 8747924
271 + 8747653 = 8747924
307 + 8747617 = 8747924
397 + 8747527 = 8747924

Showing the first eight; more decompositions exist.
