Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641770, here are decompositions:

23 + 8641747 = 8641770
29 + 8641741 = 8641770
37 + 8641733 = 8641770
61 + 8641709 = 8641770
73 + 8641697 = 8641770
97 + 8641673 = 8641770
101 + 8641669 = 8641770
127 + 8641643 = 8641770

Showing the first eight; more decompositions exist.
