Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741420, here are decompositions:

19 + 8741401 = 8741420
67 + 8741353 = 8741420
73 + 8741347 = 8741420
151 + 8741269 = 8741420
229 + 8741191 = 8741420
271 + 8741149 = 8741420
277 + 8741143 = 8741420
283 + 8741137 = 8741420

Showing the first eight; more decompositions exist.
