Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611992, here are decompositions:

5 + 8611987 = 8611992
23 + 8611969 = 8611992
31 + 8611961 = 8611992
89 + 8611903 = 8611992
101 + 8611891 = 8611992
113 + 8611879 = 8611992
163 + 8611829 = 8611992
173 + 8611819 = 8611992

Showing the first eight; more decompositions exist.
