Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749984, here are decompositions:

3 + 8749981 = 8749984
137 + 8749847 = 8749984
167 + 8749817 = 8749984
197 + 8749787 = 8749984
233 + 8749751 = 8749984
251 + 8749733 = 8749984
563 + 8749421 = 8749984
641 + 8749343 = 8749984

Showing the first eight; more decompositions exist.
