Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720348, here are decompositions:

31 + 8720317 = 8720348
37 + 8720311 = 8720348
67 + 8720281 = 8720348
157 + 8720191 = 8720348
211 + 8720137 = 8720348
229 + 8720119 = 8720348
277 + 8720071 = 8720348
349 + 8719999 = 8720348

Showing the first eight; more decompositions exist.
