Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749836, here are decompositions:

19 + 8749817 = 8749836
23 + 8749813 = 8749836
47 + 8749789 = 8749836
83 + 8749753 = 8749836
103 + 8749733 = 8749836
167 + 8749669 = 8749836
223 + 8749613 = 8749836
229 + 8749607 = 8749836

Showing the first eight; more decompositions exist.
