Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640160, here are decompositions:

101 + 8640059 = 8640160
173 + 8639987 = 8640160
239 + 8639921 = 8640160
251 + 8639909 = 8640160
257 + 8639903 = 8640160
311 + 8639849 = 8640160
449 + 8639711 = 8640160
521 + 8639639 = 8640160

Showing the first eight; more decompositions exist.
