Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719370, here are decompositions:

3 + 8719367 = 8719370
43 + 8719327 = 8719370
67 + 8719303 = 8719370
97 + 8719273 = 8719370
109 + 8719261 = 8719370
151 + 8719219 = 8719370
157 + 8719213 = 8719370
193 + 8719177 = 8719370

Showing the first eight; more decompositions exist.
