Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611982, here are decompositions:

13 + 8611969 = 8611982
79 + 8611903 = 8611982
103 + 8611879 = 8611982
109 + 8611873 = 8611982
163 + 8611819 = 8611982
193 + 8611789 = 8611982
199 + 8611783 = 8611982
349 + 8611633 = 8611982

Showing the first eight; more decompositions exist.
