Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653984, here are decompositions:

47 + 8653937 = 8653984
107 + 8653877 = 8653984
137 + 8653847 = 8653984
167 + 8653817 = 8653984
173 + 8653811 = 8653984
281 + 8653703 = 8653984
293 + 8653691 = 8653984
431 + 8653553 = 8653984

Showing the first eight; more decompositions exist.
