Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709380, here are decompositions:

3 + 8709377 = 8709380
7 + 8709373 = 8709380
19 + 8709361 = 8709380
67 + 8709313 = 8709380
79 + 8709301 = 8709380
109 + 8709271 = 8709380
151 + 8709229 = 8709380
193 + 8709187 = 8709380

Showing the first eight; more decompositions exist.
