Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749370, here are decompositions:

13 + 8749357 = 8749370
61 + 8749309 = 8749370
127 + 8749243 = 8749370
151 + 8749219 = 8749370
163 + 8749207 = 8749370
229 + 8749141 = 8749370
283 + 8749087 = 8749370
379 + 8748991 = 8749370

Showing the first eight; more decompositions exist.
