Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749986, here are decompositions:

5 + 8749981 = 8749986
59 + 8749927 = 8749986
83 + 8749903 = 8749986
139 + 8749847 = 8749986
149 + 8749837 = 8749986
173 + 8749813 = 8749986
197 + 8749789 = 8749986
199 + 8749787 = 8749986

Showing the first eight; more decompositions exist.
