Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670390, here are decompositions:

17 + 8670373 = 8670390
19 + 8670371 = 8670390
37 + 8670353 = 8670390
59 + 8670331 = 8670390
89 + 8670301 = 8670390
109 + 8670281 = 8670390
151 + 8670239 = 8670390
193 + 8670197 = 8670390

Showing the first eight; more decompositions exist.
