Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611842, here are decompositions:

13 + 8611829 = 8611842
23 + 8611819 = 8611842
53 + 8611789 = 8611842
59 + 8611783 = 8611842
139 + 8611703 = 8611842
163 + 8611679 = 8611842
179 + 8611663 = 8611842
199 + 8611643 = 8611842

Showing the first eight; more decompositions exist.
