Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661116, here are decompositions:

67 + 8661049 = 8661116
73 + 8661043 = 8661116
229 + 8660887 = 8661116
349 + 8660767 = 8661116
433 + 8660683 = 8661116
463 + 8660653 = 8661116
547 + 8660569 = 8661116
577 + 8660539 = 8661116

Showing the first eight; more decompositions exist.
