Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670372, here are decompositions:

19 + 8670353 = 8670372
41 + 8670331 = 8670372
59 + 8670313 = 8670372
71 + 8670301 = 8670372
181 + 8670191 = 8670372
283 + 8670089 = 8670372
331 + 8670041 = 8670372
379 + 8669993 = 8670372

Showing the first eight; more decompositions exist.
