Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749386, here are decompositions:

29 + 8749357 = 8749386
43 + 8749343 = 8749386
157 + 8749229 = 8749386
167 + 8749219 = 8749386
179 + 8749207 = 8749386
223 + 8749163 = 8749386
337 + 8749049 = 8749386
367 + 8749019 = 8749386

Showing the first eight; more decompositions exist.
