Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605780, here are decompositions:

47 + 8605733 = 8605780
89 + 8605691 = 8605780
173 + 8605607 = 8605780
179 + 8605601 = 8605780
251 + 8605529 = 8605780
269 + 8605511 = 8605780
311 + 8605469 = 8605780
317 + 8605463 = 8605780

Showing the first eight; more decompositions exist.
