Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618772, here are decompositions:

13 + 8618759 = 8618772
23 + 8618749 = 8618772
73 + 8618699 = 8618772
83 + 8618689 = 8618772
89 + 8618683 = 8618772
179 + 8618593 = 8618772
181 + 8618591 = 8618772
191 + 8618581 = 8618772

Showing the first eight; more decompositions exist.
