Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605722, here are decompositions:

31 + 8605691 = 8605722
113 + 8605609 = 8605722
179 + 8605543 = 8605722
193 + 8605529 = 8605722
211 + 8605511 = 8605722
241 + 8605481 = 8605722
311 + 8605411 = 8605722
353 + 8605369 = 8605722

Showing the first eight; more decompositions exist.
