Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750420, here are decompositions:

43 + 8750377 = 8750420
73 + 8750347 = 8750420
79 + 8750341 = 8750420
127 + 8750293 = 8750420
181 + 8750239 = 8750420
193 + 8750227 = 8750420
223 + 8750197 = 8750420
229 + 8750191 = 8750420

Showing the first eight; more decompositions exist.
