Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611984, here are decompositions:

23 + 8611961 = 8611984
137 + 8611847 = 8611984
191 + 8611793 = 8611984
263 + 8611721 = 8611984
281 + 8611703 = 8611984
317 + 8611667 = 8611984
383 + 8611601 = 8611984
461 + 8611523 = 8611984

Showing the first eight; more decompositions exist.
