Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670728, here are decompositions:

19 + 8670709 = 8670728
61 + 8670667 = 8670728
109 + 8670619 = 8670728
139 + 8670589 = 8670728
229 + 8670499 = 8670728
277 + 8670451 = 8670728
331 + 8670397 = 8670728
397 + 8670331 = 8670728

Showing the first eight; more decompositions exist.
