Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741772, here are decompositions:

19 + 8741753 = 8741772
23 + 8741749 = 8741772
29 + 8741743 = 8741772
31 + 8741741 = 8741772
73 + 8741699 = 8741772
89 + 8741683 = 8741772
131 + 8741641 = 8741772
163 + 8741609 = 8741772

Showing the first eight; more decompositions exist.
