Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661764, here are decompositions:

31 + 8661733 = 8661764
37 + 8661727 = 8661764
61 + 8661703 = 8661764
193 + 8661571 = 8661764
211 + 8661553 = 8661764
277 + 8661487 = 8661764
337 + 8661427 = 8661764
523 + 8661241 = 8661764

Showing the first eight; more decompositions exist.
