Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611960, here are decompositions:

101 + 8611859 = 8611960
113 + 8611847 = 8611960
131 + 8611829 = 8611960
167 + 8611793 = 8611960
239 + 8611721 = 8611960
251 + 8611709 = 8611960
257 + 8611703 = 8611960
263 + 8611697 = 8611960

Showing the first eight; more decompositions exist.
