Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611884, here are decompositions:

5 + 8611879 = 8611884
11 + 8611873 = 8611884
37 + 8611847 = 8611884
101 + 8611783 = 8611884
163 + 8611721 = 8611884
181 + 8611703 = 8611884
241 + 8611643 = 8611884
251 + 8611633 = 8611884

Showing the first eight; more decompositions exist.
