Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750228, here are decompositions:

31 + 8750197 = 8750228
37 + 8750191 = 8750228
127 + 8750101 = 8750228
181 + 8750047 = 8750228
211 + 8750017 = 8750228
307 + 8749921 = 8750228
337 + 8749891 = 8750228
439 + 8749789 = 8750228

Showing the first eight; more decompositions exist.
