Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605984, here are decompositions:

53 + 8605931 = 8605984
71 + 8605913 = 8605984
113 + 8605871 = 8605984
131 + 8605853 = 8605984
173 + 8605811 = 8605984
251 + 8605733 = 8605984
293 + 8605691 = 8605984
347 + 8605637 = 8605984

Showing the first eight; more decompositions exist.
