Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749250, here are decompositions:

7 + 8749243 = 8749250
31 + 8749219 = 8749250
43 + 8749207 = 8749250
109 + 8749141 = 8749250
163 + 8749087 = 8749250
271 + 8748979 = 8749250
277 + 8748973 = 8749250
373 + 8748877 = 8749250

Showing the first eight; more decompositions exist.
