Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719422, here are decompositions:

31 + 8719391 = 8719422
43 + 8719379 = 8719422
73 + 8719349 = 8719422
149 + 8719273 = 8719422
199 + 8719223 = 8719422
211 + 8719211 = 8719422
223 + 8719199 = 8719422
263 + 8719159 = 8719422

Showing the first eight; more decompositions exist.
