Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720354, here are decompositions:

7 + 8720347 = 8720354
37 + 8720317 = 8720354
43 + 8720311 = 8720354
73 + 8720281 = 8720354
127 + 8720227 = 8720354
163 + 8720191 = 8720354
193 + 8720161 = 8720354
241 + 8720113 = 8720354

Showing the first eight; more decompositions exist.
